The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.1.2
and the compiler used in kernel assembly: 4.1.2
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder /lib/modules/2.6.20-15-generic/build
However some compilations and executable functions may need additional files,
in the FileNames.h (so called kernel "h"eaders) collection installed in /usr/include/ .
For martian_modem, additional required packages are needed. The also required headers of package libc6 are commonly installed by default.
Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev packages, for kernels 2.6.24 and later versions.
In not included on your install CD, search for them at http://packages.ubuntu.com
or comparable Repository for other Linux distros.
When compiling ALSA drivers, the utility "patch" will also be needed.
If a driver compilation fails, with message including some lack of some FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include. The minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev
If an alternate ethernet connection is available,
$ apt-get update
$ apt-get -s install linux-kernel-devel
will install needed packages.
For Debian/Ubuntu related distributions, run the following command to display the needed package list:
Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:

COMPILING DRIVERS, for Linux Newbies
Within the workshop there is an instruction set, the Makefile, and a few tools. You command:
make clean
An elf named "make" comes in, reads Makefile and then cleans up any debris of previous efforts.
Do ALWAYS command "make clean" as a first step before new driver compilations.
The major work of compiling drivers and any associated tools is commanded with:
make
or perhaps
make DriverName
There only remains to command installation of the modem driver(s) and tools with:
make install
Configuration of a dialout utility is done elsewhere, and you can access the Internet.
It is really that simple, once the workshop with tools has been prepared.
But new drivers have to be compiled with every operaing system update.
The remainder of this text is thus aids you in the preparations, dealing with a variety of special cases.
Most points are covered in much more detail in the Linux Kernel-HOWTO, likely included among the
HOWTO documentation set installed within /usr/share/doc/ folders.
The core operating system of a PC is comprised of a motherboard, the software kernel,
and its auxilliary code modules. The kernel is the file /boot/vmlinuz-2.6.20-15-generic.
Modules located in subfolders of /lib/modules/2.6.20-15-generic/ . They can be inserted into or removed
from the acting kernel upon demand. This provides adaptablity to the diverse
hardware components of PCs and changing requirments.
Modem drivers are one type of module. As contrasted to most Linux software, modem driver codes have
some non-public code components. That is the drivers are not fully Open Source, to protect
Intellectual Property of the providing companies. This has a consequence that many Linux distributions
will not or cannot legally supply proprietary modem drivers. Rather the Users must get the
modem code package and direct compiling of the code and driver installation.
A complementary resource for compiling is a family of FileNames.h, collectively called kernel-headers.
They are both code bits themselves and also call for other code bits their functioning depends on.
Depending on the Linux distribution, kernel-headers may not be automatically installed.
If not they will always be made available on installation media or some Linux repository.
They can be searched for by package names including: kernel-source, linux-source, kernel-headers and 44
There are always some kernel-headers in afolder /usr/include/. But these are an INCOMPLETE, too small collection
and DO NOT suffice for compiling processes.
In addition some software utilities may have to be installed. The instructions for compiling are read by make.
A set of compiler tools are installed as a gcc-SomeVersion package. After compiling, the various pieces
and linked dynamically together with "ld". Together wiith some simpler software tools, the ld will
already be installed on Linux systems. Systems using the Debian style maintanence system
additionally require a package "kernel-kbuild-3.n" to properly utilize kernel-headers or 2.6.n kernels.
The "kernel-headers" are matched with an installed kernel, or must be generated from a kernel-source package.
These are provided in different ways by the various Linux distributions, under 2.6.n kernels:
Redhat and Fedora - installation is coincident with kernel installation,
with placement of the kernel-header base folder in /lib/modules/2.6.20-15-generic/build/
Mandrake and SuSE/Novell - installation as part of a kernel-source or linux-source packages,
with location at /usr/src/kernel-headers-2.6.20-15-generic or /usr/src/linux-2.6.20-15-generic
Debian and distros using its Package.deb format have names:
kernel-headers-2.6.20-15-generic
linux-headers-2.6.20-15-generic for Ubuntu
and installation is into /usr/src/
for Xandros, there is a xandros-kernel-source-version.deb which has to be installed
Unpack if necessary with
# cd /usr/src/
# ls
# tar jxf xandros-kernel-source-version.tar.bz2
see http://support.xandros.com/kb-view.php?topic=64 for details
but for 2.6.n kernels, the step after:
# make EXTRAVERSION=-x1 oldconfig
should be
# make EXTRAVERSION=-x1 bzImage
Others - ???
For the prior generation of 2.4.n kernels, there are special cases. Skip this if your kernel is a 2.6.n or a Debian type.
For RPM using distros, the kernel-source-2.6.20-15-generic or linux-source-2.6.20-15-generic packages must be installed and configured as described below:
1) SuSE with KernelVersion 2.4.21-144-* or later - install the matching kernel-source package, which does also contain the kernel-headers;
2) for Fedora II or later, kernel-headers are/were coinstalled with the kernel package;
3) for all other cases of 2.4.n kernels, the kernel-headers must be prepared from kernel-source.
The preparation can be summarised in a few steps/actions:
Install a kernel-source package representing your kernel.
Change directory (cd) into its base folder. The kernel-source in general
will match only one of several kernels that could have been installed
and NOT necessarily yours. Thus clean out any remnants of earlier usages with:
make mrproper
Copy in your kernel configuration file and have it read with:
make oldconfig
If necessary edit ONLY the fourth line of the Makefile, which completes
the specification of where drivers will be installed to (details below).
The kernel-headers are then assembelled by either:
a) for 2.4.nn kernels by
make dep
b) for 2.6.n kernels,
make bzImage
which includes an integral "make dep" step.
Modem related resources may or may not have been installed during the primary Linux installation,
as WinModem hardware is often NOT recognized. Search your Distro's package
descriptions for "modem" to reveal the status of related resources. Read
the package description to determine whether pre-compiled modem drivers were provided.
RESOURCES of a few types are needed to get on line. Do PREFERABLE use your System's
package maintenance system for the installation. This should guarantee that
any DEPENDENT packages will be called into the installation process. As a preliminary
1) Install your distributions package providing the KPPP, WVDIAL and MINICOM dialer utilities.
Dependencies within such packages will also drive the unpacking of ppp related modules
from compressed to a functional form :
module.o.gz --> modules.o
or for 2.6.n kernels
module.ko.gz --> module.ko
In addition these dialers will later aid testing and configuration,
which is to be performed only AFTER, the modem's drivers are installed.
2) Download if necessary and modem driver package specific to your modem hardware.
3a) Install if necessary your distrbution's kernel-source package, necessary for preparing kernel-headers under 2.4.n kernels
Or for Debian style distributions,
3b) install the kernel-header-2.6.20-15-generic.deb package matching your kernel version 2.6.20-15-generic.
A KERNEL-SOURCE package must be installed, if a full kernel-header set
is not otherwise provided. Kernel-source packages are now some 30-40 MB now even in compressed form.
The package provided by your Linux Distro SHOULD preferentially be used.
It will usually have some differences from that initially released at http://www.kernel.org .
Typically the installation process will set two symbolic links:
/lib/modules/2.6.20-15-generic/build --> PATH_to/kernel-source-version/
/usr/src/linux --> PATH_to/kernel-source-version/
These later enable access to the kernel-headers needed during the modem driver compiling. Check with:
ls -l /lib/modules/2.6.20-15-generic/build
ls -l /usr/src/linux
The former link is more usefull for Systems with alternative boot kernels,
and is mandatory for some modem compiler packages.
HIGHLY IMPORTANT: the kernel-source as installed in generally does NOT
represent your current kernel version, EVEN if the kernel-version is the same.
Only one of several possible kernels was installed on your System,
and the unpacked kernel-source need NOT represent it exactly!!!
For example, in the RedHat Distro there is a set of kernel-configuration files within
/usr/src/linux/configs/
Each is specialized for a different CPU (i586, i686, K6, etc),
Yet each will be represented by the VERY SAME version name: "uname -r" .
!!!! Thus a PROPER CONFIGURATION MUST BE DONE by You, before compiling drivers !!!!
Examples provided below are partially customized from your System settings.
CONFIGURATION is started by moving into the kernel-source folder with one of:
cd /lib/modules/2.6.20-15-generic/build
cd /usr/src/linux
There is a Makefile on your System at: /lib/modules/2.6.20-15-generic/build/Makefile
with first few lines:
VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 20
EXTRAVERSION=-15-generic
NAME = Homicidal Dwarf Hamster
ifdef UBUNTUBUILD
For your current kernel, the fourth line should be
EXTRAVERSION =
where has been read from your current kernel version: 2.6.20-15-generic.
But it this does not match what is Actually in the Makefile,
then it represents a Different kernel-header set then that of your kernel!!!
For Mandrake Linux their will generally be an included "mdk", such as:
EXTRAVERSION = -3.1mdk
SuSE 9.0 had:
EXTRAVERSION = -99-default
The first four makefile lines specify that:
a) the compiled kernel modules/drivers will have encoded version labels such as:
2.4.21-3.1mkd OR 2.4.21-99-default
b) such modules including modem drivers are installed into sub-folders of
/lib/modules/2.4.21-3.1mkd/
/lib/modules/2.4.21-99-default/
The major points are that compiled drivers must be both
kernel-release (the 2.4.21) AND EXTRAVERSION matched with the installed kernel.
Otherwise they may be installed uselessly and not be detected by the kernel
OR there will be a failure upon attempted insertion, with message including:
a list of "unresolved symbols ".
Kernel-headers may be resident from a prior usage of the kernel-source/.
Check with:
ls include/linux/
which may display abundant FileNames.h
The version of these headers will be in the UTS line displayed by
cat include/linux/version.h
#define UTS_RELEASE "2.4.21-3.1mdk" (as an example)
Next, list completely the contents of the kernel-source with:
ls -a
Where the " -a " additionally reveals ".dot-prefixed-confguration-files" such as
.config .hdepend .depends
which may be left over from the prior usage of the kernel-source. Below is an example:
-------------------
.config .hdepend .depends
COPYING Makefile Rules.make init mm
CREDITS README arch drivers ipc net
Documentation conf.vars fs kernel scripts
MAINTAINERS REPORTING-BUGS crypto include lib
Configuration of the kernel-source is where almost all the Mistakes occur!!!
Here is a way to do it correctly (but read through EXCEPTIONAL CASES below).
1)Within kernel-source/ folder, browse the README file for general guidance.
It will relate that the command:
# make mrproper
cleans up leftovers from any previous usage .dot-files and the include/linux/ folder.
Additionally you may need to do an edit within Makefile, but ONLY that 4th line.
2) If necessary to edit, FIRST make a backup:
cp Makefile Makefile.backup
then edit ONLY the 4th line of Makefile to match the EXTRAVERSION of 2.6.20-15-generic
EXTRAVERSION = -
NEVER change anything else within the Makefile.
3) Set the dependencies of the current kernel.
For SuSE 9.0 and later, there is a command which does the following steps
# make cloneconfig && make dep
Also browse the excellent README.SuSE in the kernel-source/ folder
For other Distros, the following steps are necessary, within the kernel-source/ folder
copy the kernel-config file to .config
and DO SPECIFY that " . "
But where is it? For many Distros, it will be the file like
/boot/config-2.6.20-15-generic
matching the output of:
uname -r
Or it may be the target of a symbolic link: /boot/config -->
So
cp /boot/config-2.6.20-15-generic .config
For SuSE 8.0 and earlier versions it is:
cp /boot/vmlinuz.config .config
PLEASE do not omit that "." in .config as it is crucially necessary.
View .config with a text browser.
It is simply a listing of the code components used in the kernel and its modules:
#
# Automatically generated make config: don't edit
#
CONFIG_X86=y
# CONFIG_SBUS is not set
CONFIG_UID16=y
etc.
4) The .config file will be read during
# make oldconfig
which feeds its specifications through a process specifying
the SAME inter-dependencies previously used in compiling your kernel,
and may generate additional .dot-config files . They can be displayed with:
# ls -al
5) Though it may be redundant after "make mrproper", it will do no harm to:
make clean
5a) For the SuSe Linux versions 8.0 and previous , there will exist files:
/boot/vmlinuz.autoconf.h
/boot/vmlinuz.version.h
They MUST be copied as:
cp /boot/vmlinuz.autoconf.h /usr/src/linux/include/linux/autoconf.h
cp /boot/vmlinuz.version.h /usr/src/linux/include/linux/version.h
6) Now build kernel-headers with:
make dep
for 2.4.n kernels or for 2.6.n kernels
make bzImage
during which you can walk your dog, take a shower, have tea, etc.
7) Check for resultant FileNames.h with:
ls include/linux/
and
cat include/linux/version.h
to verify the version.
COMPILING the MODEM DRIVERS can now finally be done.
Unpack the compiler kit for your modem drivers,
cd into its folder, read any README or INSTALL files,
make clean
FINALLY, your modem drivers will compiled by a command like
make OR make ModuleName
or perhaps
make all
During this process, some of the kernel-header code with be joined
with the supplied modem specific code, and ModemDrivers.o will be produced.
Follow and further instructions in the modem code resource
to install the drivers, often with:
make install
THEORETICAL ISSUES
WinModem driver packages commonly include:
1) a readible Open Source component, which can be readily debugged by
experts in code. This component provides "wrappers" to common
kernel functions for an already complied, or BINARY format, component of the modem code.
2) A Closed Source component compiled into the binary form, in which
proprietary information is encrypted. This will include the copyrighted Vn.nn compression algorithms.
In 2004, pre-compiled modem drivers are beginning to be included
for a few winmodems by some Linux distributions.
But the binary format precludes incorporation of the modem drivers in some Linux distributions
for legal reasons, practical reasons, and/or reasons of principle.
Since almost all the newer PCs are now equipped with WinModems,
many users will have to compile their own linux modem drivers.
Exceptions are the more expensive modems with Controller chipsets,
characteristic of the earliest modems.
They are supported by Open Source serial code included in Linux
distributions (Distros hereafter).
Winmodems are less expensive because of greatly reduced hardware costs.
They lack Controller chips of the earliest modems, and may additionally lack Digital Signal Processor (DSP) chips of second generation modems.
Functions of Controller based chipsets are replaced by a combination of
software code and/or other System hardware.
Modems without a controller chip are referred to as "controllerless modems" and
modems lacking both a DSP and controller chips are referred to as "soft modems".
With faster central processor units (CPU), some processing tasks are performed
by the CPU for the controllerless modems. The CPU does nearly all
the signal processing for the "soft modems" lacking a DSP.
AC97 or MC97 soft modems conform to an ac97_codec, and can host a variety of Subsystems It is the CODEC of the Subsystem which determines which software should be utilized!!
and any modem controllers can host one of a variety of soft modem Subsystems.
There are additionally soft PCI modems without such controllers, which still utilize
the common ac97_modem.o driver. In general it will be YOUR task to identify
the Subsystem codec and compile the needed driver.

Also see http://freewebhosting.hostdepartment.com/g/gromitkc/pcmcia_list.html
The 3COM,Inc 3CXM556 and AgereSystems FM560LK chip modems use Open Source serial-cs.o drivers.
For modems not recognized by scanModem, chipset information may be obtained under Microsoft Windows through:
1) Start > Settings > Control Panel > Classical View (for WinXP) > Modem
or alternatively under Linux
# cat /proc/asound/mc97*
Try to identify the modem setup file, with name perhaps MODEM.INF
2) Open a COMM console, and send ATI commands to the modem (ATI, ATI1, ATI2, etc)
which may elicit chipset and driver information. Here is an example

SUPPORT SUMMARY - as of 2009_05_12
-------------------------------------
Controller chipsets are used in the most expensive modems and are supported.
They utilize the same serial drivers included with kernel+module installations,
and most commonly one of the ports /dev/ttyS0 thru 3.
Such chipsets are produced by 3Com, AgereSystems (the Venus chipset),
Topic Semiconductor Corp., and others. But the same companies may
produce unsupported WinModems. Do not depend on the Brand Name.
Look for an explicit statement of Linux support
AVOID the following modem chipsets:
ESS - no formal support since 2.2.2 kernels, though there are kluges:
http://andywettstein.home.comcast.net/ess/
http://tx.technion.ac.il/~raindel/
3Com/US Robotics winmodems - never supported under Linux
SmartLink - newer chipsets are supported: http://www.smlink.com
ftp://ftp.smlink.com/linux/unsupported/
Moreover, the slmodem-2.9.10 drivers will support Many but not all modem Ssubsystems
that serve under AC97/MC97 controllers.
Conexant - all modems supported with drivers at: http://www.linuxant.com
Testcode for slow 14,400 mH support is free, BUT
there is a one time charge for the full speed support.
Intel Inc. - http://developer.intel.com/design/modems/support/drivers.htm
For early releases check at: http://linmodems.technion.ac.il/resources.html
The HaM modem is supported, but code is no longer being updated;
there will likely be failures under emerging 2.6 kernels.
The 536EP and five Intel537 modem chipset variants are actively supported.
Lucent /AgereSystems
The Venus chipset modem uses the Linux seraik drivers and is thus supported.
Modems with digital signal processing (DSP) chipsets are supported: http:/ltmodem.heby.de
For AC97/MC97 soft modems. Initiate software access through code sponsor IBM:
http://www-3.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-52698
Coding of support for has Not yet begun PCI soft modems with PCI_IDs 11c1:048?
Motorola support is at: http://www.motorola.com/softmodem/sm56_download.htm
through 2.4.22 kernels.
PCTel modem business has been sold to Conexant
Driver compiler resources are at: http://pctelcompdb.sourceforge.net/
However, the pre-compiled binary component is yet to be assembled
with the gcc 3.nn used in newer Linux releases,
so forced (-f) insertions may be necessary:
insmod -f pctel
Some of the HSP soft modems are supported by the SmartLink slmodem-2.9.10 drivers.
Broadcom modems in Dell laptops and PCs - can be made to function under 2.4 kernels, but code has not been updated recently.
--------- end chipset section ----------------------
SUPPORT under the current 2.6.nn kernels.
The more expensive Controller chipset modems are functioning.
SmartLink slmodem-2.9.9 drivers are functioning.
Conexant has 2.6.n support
The Lucent/Agere digital signal processing (DSP) chipsets do have
informal service into 2.6.n kernels and an AgereSystems release is soon expected.
Intel, Agere Systems and Linuxant are firmly expected to continue support into 2.6.nn,
though the Intel HaM software will not be updated to 2.6.n service
------------------------------------
Preparing winmodem drivers will generally require compiling.
If you are not familar with this process DEFINITELY read carefully
the Modem/DOCs/DriverCompiling.txt
RATIONAL
This scanModem service is sadly necessary because of the pre-compiled format
(binary, Closed Source) of some modem supporting code. Intellectual property
is protected within the binary component. But this prevents compatibility
assessments/debugging against Linux Open Source code. Skipping many details,
the consequence is that some Linux distributions do not deliver Closed Source code,
or tools adequate to fully identify the modem chipset.
This script tries to close this information gap.
This script primarily utilizes the "lspci" utility from the package PCIUTILS.
Various component scriptlets interpret the information captured by lspci.
For many modems, directions to supporting software and/or more detailed information is enabled.
ISA bus modems, 16 bit PCMCIA card modems and USB modems will not be recognized.
See the output files for guidance on these cases.
The script originated as scanPCI written by Chris Hebeisen,
to recognize modems with DSP (digital signal processing) chipsets made by Lucent/AgereSystems.
It now aspires to provide useful information on other modems as well.
For the Lucent/Agere DSP chip modems, System information is used to recommend Installers,
from the Installer list output from the repository: http://ltmodem.heby.de/
For other modem chipsets fully identified, URLs to support sites are given.
Three types of information are acquired from your System:
1) General system information necessary for your guidance;
2) The PCI_ID of the modem card, or for the increasingly prevalent "soft modems",
the PCI_IDs of its AC97/MC97 controller and its modem subsystem.
3) For soft modems, a SIL_ID of the subsystem is either acquired
OR instructions provided for manual agetting it.
The remainder of /media/KINSTON TOW/scanModem/scanModem.2009051256 is a repository of "modem gossip" or URLs thereto.
Only information blocks most relevant to your System will be output into
files written to the Modem/ folder
Should you need assistance after FIRST following all the advice and/or URLs,
1) Browse the general information at: http://linmodems.technion.ac.il/
2) ONLY thereafter send ModemData.txt to: discuss@xxxxxxxxxxxxx
Modem/DOCs/General.txt has common information the List need not be bothered with.
3) Also the archive SEARCH ENGINE at http://linmodems.technion.ac.il/
may be useful once PCI or SIL IDs are acquired.
The scanModem script can be read and word searched with a text browser.
Blocks of Information with little code begin and end with #####.
In case of a failure concerning "lspci", rerun /media/KINSTON TOW/scanModem/scanModem.2009051256 after login to a console with
# su - root
as Root permission may be necessary for access to lspci.

Modem Type Readout and Supporting Software Identification.
-------------------------------------------------------
Most add on cards to motherboards (including modems) adhere to a PCI standard, for
which there is firmware on the card which can be readout, providing setup parameters
and specification of the required software. This works under Linux provided that
drivers are resident. Herein is the practical problem. During the evolution of
modems, some of the complementing software components became Proprietary and
Closed Source. A consequence is that for reasons of Legality and/or Principle,
many Linux distributions do not distribute such modem drivers with the regular
releases, even when the modem chipset designer does provide Linux support code.
Without the drivers, additional assistance is needed to identify the modem
chipset and its complementing software.
The scanModem script includes four routines to determine the software required:
1) Readouts with a lspci tool accessing firmware on PCI cards.
2) A test using modem drivers already on your system as part of the ALSA (Advanced Linux
Sound Architecture) software package. See DOCs/Smartlink.txt for details.
3) Comparison of Primary+Subsystem PCI IDs with others historically gathered, and
then archived within scanModem.
4) A test requiring the SmartLink slamr.ko driver. See DOCs/Smartlink.txt for details.
Should these not be adequate, there are directions below for doing diagnostics during
an alernate Microsoft Windows bootup.
Stop here on a first reading, and just run
./scanModem
Read on later if you are interested in details, OR
need instructions for doing modem diagnostics under Microsoft.
Using MicroSoft(MS) Windows:
-----------------------------
MS installations do generally have adequate diagostic capability. Try the following
routine 1), beginning with mouse clicks on:
1) Start > Settings > Control Panel > Classical View (for Window XP) > System
> Hardware > Device Manager > Modems > Click on the + > Modem. Double click to
expand the graphic. Manufacturer information may be displayed. For example, CXT
stands for Conexant. Click the Diagnostics Tab. Record any hardware ID or vendor
and device information.
Next do the Query Modem and record the ATI specifications displayed such as:
ATI3 - Agere SoftModem Version 2.1.22
ATI5 - 2.1.22, AMR Intel MB, AC97 ID:SIL REV:0x27
Try to identify the modem setup file, with name perhaps MODEM.INF.
2) Open a COMM console. Send ATI commands to the modem (ATI, ATI1, ATI2, etc)
which may elicit chipset and driver information. Here is an example:
ATI3 - Agere SoftModem Version 2.1.22
ATI5 - 2.1.22, AMR Intel MB, AC97 ID:SIL REV:0x27
successfully identifying an Agere SoftModem chipset, both by name and through
the softmodem SIL ID: AC97 ID:SIL REV:0x27
The IBM mwave modem:
This has a DSP chip usually seated on the motherboard. Not carried on a PCI card
it cannot be detected by scanModem. However, the mwave driver is included in
2.6.n kernel releases.
So try:
# modprobe mwave
Either the module will load or the absence of the modem will be indicated by:
FATAL: Error inserting mwave (/lib/modules/2.6.10-1-
686/kernel/drivers/char/mwave/mwave.ko): Input/output error
See http://www.linuxdocs.org/HOWTOs/mini/ACP-Modem/ for details on this modem.
Modem evolution:
----------------
Here is a very abbreviated history on how modem evolutionary development. The
earliest modems (MOdulate and DEModulate signals for phone lines transmission)
managed all signal proceesing on the modem card through actions of expensive
Controllers chipsets with DSP (digital signal processing) capability. Copyrighted
Vn.nm compression routines were also encoded in the chipset. Under Linux, an Open
Source serial driver was the minimal complementing software. This generation of
Controller chipset modems placed minimal burden on the early slow central
processing unips (CPU) of personal computers, such as the Intel 386.
As CPUs became faster, it was feasible to transfer some modem functions to
the CPU. A 2nd generation of modems retained a DSP chip, but Controller functions
were software driven on the CPU. A benefit was that modem hardware became cheaper.
But sadly the supporting software was Proprietary. Worst, some Intellectual Property
components were Closed Source to protect large investment in code development. Such
Controller free modems include the Conexant HCF, Intel-537EP and Mars chipset
modems from Lucent or its later subsidary, Agere Systems Inc.
As CPUs became even faster, even DSP functions could be software code driven on
the CPU. This third generation of modems are commonly called "softmodems". Their
complementing software is comparable in sizeto that of the Linux kernel itself. The
residual "modem chip" is very cheap, but the development of the complementing
software is a large investment on the part of the chip designer/maker.
Modem chipset determination under Linux:
---------------------------------------
The chipset of a modem determines which complementing software is required.
The Manufacturer and Model of an assembled modem are often inadequate to identify
the chipset. But sometimes there is an easy chipset identification. There is
a "lspci" utility provided in the Linux pciutils package. It reports the PCI
identifiers (IDs hereafter) or the Primary card, its Subsystem, and some setup
parameters written in firmware. For example, there is a softmodem in the
PCI bus of address 00:11.6 on my laptop. Shown below is firmware information
acquired by two lspci commands:
$ lspci -s 00:11.6
00:11.6 Communication controller: VIA Technologies, Inc. AC'97 Modem Controller
$ lspci -s 00:11.6 -nv
00:11.6 0780: 1106:3068 (rev 80)
Subsystem: 14ff:100b
Flags: medium devsel, IRQ 193
I/O ports at e000 [size=256]
The translation is: The card inserted into PCI bus slot 00:11.6 is named
"Communication controller: VIA Technologies, Inc. AC'97 Modem Controller". The
modem was assembled by a Vendor with ID identification code 1106 . Among 1106's
products, it has a Device ID of 3068 in its 80th revison. This usually provides
adequate information, to get software from the Vendor designated by 1106 (VIA
Technologies, Inc. in this case) for their device designation 3068. The parameters
Flags: medium devsel, IRQ 193
I/O ports at e000 [size=256]
are determining by the environment of the host computer as reading modem firmware.
It may change if other hardware is added/removed from the host computer, or
under a change or Operating System (OS) kernel.
The problem for softmodems is that additional information is needed for the software
specification. The Subsystem Vendor_ID identifies only the assembler company. But
the modem chip housed in the Subsystem could be of a variety of types, each requiring
different support software. In general, a single Subsystem assembler could use a
variety of different softmodem chips. The Subsystem firwmare information on the chipset
is not accessible to lspci. Rather it requires usage of a modem driver, if one first had
some competent modem driver for minimal diagnostics.
Fortunately there are the software tools and drivers of the ALSA (Advanced Linux
Sound Architecture) suite. This includes modem drivers lacking COMM proficiency by
themselves, but enough capability to readout the Subsystem firmware. For the VIA
modem above, the encoded modem codec is SIL22, reporting that the softmodem chip was
made by SmartLink Inc.
It is important to emphasis, that AC'97 Modem Controllers are made by a variety
of companies, and each may house many different Subsystem modem chips. There is
an Archive within scanModem of those with previously identified codecs. For example,
the table for the 1106:3068 AC'97 Controller is:
codec SubSystems_with_codec ------------>
CXT 104d:8143 104d:80f6 1025:0030
SIL27 1102:0033 1025:0046 1025:0033 1734:1078 1509:2870 1025:0046
SIL22 1743:1032 10cf:118e 1734:1054 1462:309e 1631:e004 1543:4c22 161f:2032 and_more
SIL21 10cf:118e 13bd:1022 1543:4c21 1071:8375 1019:0c04 1458:1543 1019:b320
MOT66 1734:109b
Because of hardware configuration issues, the ALSA tools may initially fail. Then this
Archive is a fall back reporting the codec, and therefrom the needed software. For reasons
obscure, a single Subsystem ID may have different codecs under different Primary
controllers. Thus the pair Primary+Subsystem IDs must BOTH be retained to record
the codec.
In addition to the Modem Controllers adhering to the AC'97 specifications, softmodem
Subsystems may be hosted by High Definition Audio (HDA) cards such as the:
8086:2668 Intel Corp. 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller
These lack a softmodem codec. Instead the softmodem chip information acquired with ALSA
tools is within a folder: /proc/asound/card0/codec*#1/
and includes the Vendor ID of the softmodem chip, such as 14f1 corresponding to Conexant.
The software support:
---------------------
The CXT designation above is an abbreviation of CXT_some_number, for Conexant HSF softmodem
codecs. These now number some 41 (perhaps more) CXT. Fortunately, all these codecs are
supported by a single hsfmodem software package provided through http://www.Linuxant.com
The trial package is free, but locked to speeds of 14,400 K. A software key must be
purchased to enable full speed support, with future software updates free. There is NO
freeware alternative for the hsfmodem software. But Linuxant does provide pre-compiled
drivers for the more common Linux kernels, and their support services are good.
In the Table below, there are currently some 13 other softmodem codecs. Fortunately
all are supported by a combination of the ALSA modem drivers, the ALSA audio drivers
the modem drivers depend on, and a very smart helper utility from Smartlink Inc.,
the slmodemd helper. Sasha Kharposky wrote the Linux slmodemd utility and remains its
volunteer maintainer. It provides the cleverness to interface between the low level
ALSA modem driver and the pppd package communications codes. For details do:
$ slmodemd --help
and read associated documentation. The slmodemd is provided with some Linux distributions,
and can also be downloaded in SLMODEMD packages from:
http://linmodems.technion.ac.il/packages/smartlink/
Subsystems of AC'97 Modem Controllers
---------------------------------------
Subsystems for softmodems are primarily made by Silicon Labs (SIL) under
contract to companies like Intel, Agere Systems, Motorola etc. In the Table
below, ChipMadeBy does NOT imply software support directly from that
manufacturer. The chart of information below is largely harvested from messages
to discuss@xxxxxxxxxxxxxx
A codec_indent such as REV:0x27 is reported by diagnostics under Microsoft, as
illustrated above. The matching designations such as SIL27 are translations
under Linux, which are output by a diagnostic of the slamr.ko driver from the
SmartLink slmodem software.
SIL is an abbreviation for Silicon Laboratories Inc., which provides Subsystems
on order to many modem assemblers.
SML is used below as abbreviation for SmartLink Inc. with official driver
resources at http://www.smlink.com/main/index1.php?ln=en&main_id=40 . BUT use
updated resources at http://linmodems.technion.ac.il/packages/smartlink/.
ALSA+SML means use an ALSA modem driver plus the Smartlink slmodemd helper,
with the particular driver depending on the AC'97 or HDA host controller.
ID was originally a hexadecimal readout from 7c and 7e registers of the SubSystem,
but are translated into "english", as done automatically by the slamr driver.

MODEM TESTING
This text is complemented by the Post-Install at http://linmodems.technion.ac.il
Please so consult it if the following does not suffice.
The wvdial package provides for an automated hardware+driver test.
This utility searches through ports with syntax: /dev/ttyS* (i.e. S0, S1, SL0 etc.)
and also follows a symbolic link:
/dev/modem --> /dev/ModemPort
If your modem port name does not satisfy these requirements already,
do a console login as:
su - root
Make the symbolic links as:
ln -sf /dev/ModemPort /dev/modem
ln -sf /dev/ModemPort /dev/ttyS15
wherein /dev/ttyS15 is reserved for experimental usage.
Should there be problems with wvdial version 1.54.1-1 , drop back to 1.54.0-1
For recent RedHat and Fedora releases, wvdialconf is used by the Internet Wizard.
Within the pop-up menus find the Wizard. Its actions will write a configuration file:
/etc/wvdial.conf
For other Linux distros, open a console and login with
su - root
If necessary load the modem drivers:
sudo modprobe DriverNames
Then run the test:
wvdialconf /etc/wvdial.conf
Checks /dev/modem and ports /dev/ttyS*, a success at port /dev/ttySLT0 would be:
ttySLT0<*1>: ATQ0 V1 E1 -- OK
ttySLT0<*1>: ATQ0 V1 E1 Z -- OK
ttySLT0<*1>: ATQ0 V1 E1 S0=0 -- OK
ttySLT0<*1>: ATQ0 V1 E1 S0=0 &C1 -- OK
ttySLT0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 -- OK
ttySLT0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK
etc.
The /etc/wvdial.conf written looks like:
[Dialer Defaults]
Modem = /dev/ttySLT0
Baud = 115200
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
; Phone = <Target Phone Number>
; Username = <Your Login Name>
; Password = <Your Password>
For systems using the SmartLink slmodem drivers,
the following line should be added to its /etc/wvdial.conf
Carrier Check = no
So after editing in your personal information a functional file is like:
[Dialer Defaults]
# lines beginning with # are Comments, not read by wvdial
Modem = /dev/ttySLT0
Baud = 115200
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
## if there is problem with dial tone acquisition, add into the above line:
# X3
# meaning "dial without waiting"
## for some Internet Provides, there may be problems with the new V92 mode codes.
# This can be suppresses with an:
# Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 +MS=90
## Within Italy it is sometimes necessary to even force a slower mode
# ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 +MS=34
# This mode is also useful for PBX dialout lines.
ISDN = 0
Modem Type = Analog Modem
# edit in your IP's phone number below.
Phone = 3334445555
# Do not use - or spaceds in the Phone = line
# Introducing a pause with a , is sometimes necessary with hotel/company switchboards
# Phone = 8,3334445555 or 8,,,3334445555 for s 3 second pause
Username = Your_Login_Name
# for MSN.net, use instead
# Username = MSN/Your_Login_Name
Password = Your_Password
# if not using the SmartLink slmodemd, comment out with # the following line.
Carrier Check = no
[ Dialer 2nd_home ]
Phone = 7778889999
Then dialout with
$ sudo wvdial
or use the 2nd dialup number with:
$ sudo wvdial 2nd_home
The /etc/wvdial.conf generated by the RedHat/Fedora Internet Wizard
has a different format, adapted to its own dialer. This includes a line
Stupid Mode = yes
More informative dialup feedback May be obtained if it is commented out:
# Stupid Mode = yes
A dialout with wvdial will then display like:
# wvdial &

TROUBLE SHOOTING
Check for modem driver loading.
Do FIRST read INSTRUCTIONS files provided with the modem driver resource.
Some may have installed to /usr/share/doc/Modem_or_Driver_Name/
For RPM using distros, documentation files will be listed through
rpm -q -d packageName (less the version part, sometimes)
and all directly installed files can be listed by
rpm -q -l packageName
Depending upon your installation, the modem drivers may/may_not be autoloaded.
Login as Root in a console with:
# su - root
# lsmod
If the modem drivers are not already loaded onto the kernel, insert them with command
# sudo modprobe ModuleDriver
If there are multiple drivers such as the lt_modem.o and lt_serial.o pair,
commanding the serial like driver:
# sudo modprobe lt_serial
should autoload all modules it depends on. Check with:
# lsmod
This proceeds through a reading of dependency files
written to /lib/modules/2.6.20-15-generic/ during boot up through the "depmod -a" command.
In constrast
# insmod lt_serial
would only attempt loading of that single driver and will FAIL, if its dependency on
lt_modem.o has been satisfied by prior lt_modem.o insertion.
Do read "man wvdial" and /usr/share/doc/vwdial documentation
sometime browse the documentation that is written to /usr/share/doc/wvdial/
Therein are instructions for setting up alternative dialouts.
%%% This wvdialconf action if successful generates the files:
/etc/ppp/peers/wvdial
/etc/ppp/peers/wvdial-pipe
in addition to the /etc/wvdial.conf
Many Users prefer to use the dialout utility KPPP. This is fine.
But each User MUST run the configuration process separately.
In principle, different Users on the same Linux System could
have different Internet providers and/or use different modems.
The configuration process generates a file: /home/UserFolder/.kde/share/config/kppprc
Therein, non-standard modem port names can be entered, such as:
[Modem]
Device=/dev/ttySHSF0
for the Conexant hsfmodem port.
Preparation for dialout if other COMM modes are active.
---------------------------------------------------------------------------
Concurrent ethernet capability will compete for
the Domain Name Service (DNS) needed for browser naviagation. So as root:
# /sbin/ifconfig eth0 down
before starting a dialout!
With a Mandrake installation, it will be necessary to:
# /etc/init.d/network stop
Internet clients such as Netscape, Mozilla, Explorer etc.
should be CLOSED during your first dial out trials.
Should a URL on the Internet be specifed as the default URL/connect,
then the Client may compete with ppp for connectivity functions.
After PPP functionality has been verified, the effects of opened
or launched browsers can be checked
If you have installed the DIALD (dial on demand) package, stop it for initial tests:
# /etc/init.d/diald stop
Otherwise diald function will be initiated with modem usage,
and could compilate issues. Test diald only after ppp by itself is fine.
If your internet provider assigns DNS dynamically then add to /etc/ppp/options:
usepeerdns
To analyze a dialout attempt, it is useful to display kernel messages with:
# tail -f /var/log/messages &
The & puts the commanded process in the "background" allowing recovery of the command prompt.
Some dialer packages (kppp etc) may automate the above steps.
Note that for some Linux distributions (Mandrake for one),
maintain modules in compressed module.gz format, if modem service was not specified
during the Linux installation. A subsequent installation of any dialer package:
wvdial - PPP dialer with built-in intelligence.
kppp - PPP dialer for KDE
dtmfdial - A DTMF Tone Dialer
gkdial - Gtk-based PPP dial-up configuration tool.
gkdial-gnome - GNOME-based PPP dial-up configuration tool.
masqdialer - daemon for remote control of masqueraded dialup links
pppconfig - Debian configuration toolset with command: pppconf
will stimulate unpacking of ppp related modules during bootup.
The cogent ppp related modules loaded during such a CONNECT are displayed within the output from:
# lsmod
ppp_deflate 3512 1 (autoclean)
zlib_inflate 18980 0 (autoclean) [ppp_deflate]
zlib_deflate 18648 0 (autoclean) [ppp_deflate]
bsd_comp 4440 0 (autoclean)
ppp_async 7744 1 (autoclean)
ppp_generic 16380 3 (autoclean) [ppp_deflate bsd_comp ppp_async]
slhc 5264 1 (autoclean) [ppp_generic
For ealier 2.4.nn kernels, loading of these modules may require the following lines within
/etc/module.conf :
### automate ppp modules loading ###
alias /dev/ppp ppp_generic
alias char-major-108 ppp_generic
alias tty-ldisc-3 ppp_async
alias tty-ldisc-14 ppp_synctty
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate
### end ppp block ####
For more recent kernels with their modutils,
these lines are no longer needed.
For potential causes of a NO DIALTONE failure, read the Post-install.html
at http://linmodems.technion.ac.il/ Not setting the Country Code may be
and additional problem.
COUNTRY CODE Issues
====================
The modem which you purchase locally or abroad may not be preset
with the proper Country Code setting. An incorrect setting can
hinder acquisition of dial tone.
Inclusion of an X3 (dial without wainting) in the modem Init string
of under wvdial, including in /etc/wvdial.conf a line
Stupid Mode = yes
Dialtone recognition depends on the setting of country
and/or local phone line equipment.
To properly get dialtone for your country phone experiment use
AT+GCI=xx where xx is country code in hexidecimal format.
Theoretically there could be 256 different countries but
not all are valid. Tables in manuals are way off date,
you have to write a small script to try all combinations
for yourself if you can't guess by chance.
After country select you can check textual name of the country it represents.
For example:
at+gci=00
OK
ati9
Japan
If you can't find exact country, choose the nearest one available.
Nearby countries tend to have similar equipment and compatible dialtones.
If a message like:
Sep 20 09:32:42 localhost pppd[7355]: The remote system is required to authenticate itself
is generated during an abort of a login,
Then try adding a line to /etc/ppp/options
no auth
8) After a successful CONNECT, the Domain Name Service (DNS) needed
for Browser navigation can be checked with:
# ping corel.com
PING comcast.net (63.240.76.72): 56 data bytes
64 bytes from 63.240.76.72: icmp_seq=0 ttl=52 time=209.1 ms
64 bytes from 63.240.76.72: icmp_seq=1 ttl=52 time=189.9 ms

64 bytes from 63.240.76.72: icmp_seq=3 ttl=52 time=179.9 ms
# Ctrl-C

# ping 63.240.76.72
PING 63.240.76.72 (63.240.76.72): 56 data bytes

64 bytes from 63.240.76.72: icmp_seq=2 ttl=52 time=170.0 ms
# Ctrl-C
aborts ping
Should there be a success with:
# ping 63.240.76.72
BUT a failure with the named address:
ping comcast.net
Then DNS has not been acquired.
Note that failure to stop ethernet service
# /sbin/ifconfig eth0 down
before starting a dialout, will commonly block DNS under ppp.
To terminate the wvdial session, bring the action to the foreground (fg):
# fg wvdial
Ctrl-C to terminate:
wvdial
Caught signal #2! Attempting to exit gracefully...

The Debian distribution provides a utility:
# pppconfig
for setting up a chatscript for ppp initiation.
Most dialers do use chatscripts and will produce similar records.
Below is the record of a dial out initiated by:
# pon
: pppd 2.4.1 started by marv, uid 1000
: abort on (BUSY)
: abort on (NO CARRIER)
: abort on (VOICE)
: abort on (NO DIALTONE)

Once your first CONNECT has been established, than in the future if should suffice
just to use your dialer of choice: wvdial , kppp .gnomeppp or whatever.
Good surfing to you.
10) GENERAL ITEMS
If attemped insertion of a modem driver evokes a complaint like:
unresolved symbol do_SAK_R9a0bcb74
then the kernel-headers using in compiling the modem drivers
do not match those of your current kernel whose KernelVersion is displayed by:
uname -r
and whose kernel config file is often located at /boot/config-KernelVersion
The section above "COMPILING DRIVERS, for Newbies" relates how to make corrections.
There are definitely IPs whose login protocols are Linux hostile.
If you cannot achieve a login, try another Internet Provider (IP).
or ask for someone on discuss@xxxxxxxxxxxxx to test your IP.
Many driver packages provide for loading modem drivers on bootup.
Here is a description on how to set it up, if necessary:
http://linmodems.technion.ac.il/archive-fourth/msg00451.html
PLEASE include the diagnostic output of the following Root command in any problem reports:
# setserial -agv /dev/ttyS*

Modem usage is accomplished through drivers, sometimes some helper software,
and the core communication work horse "pppd". Usually it will be found at
/usr/sbin/pppd with permissions shown on my Ubuntu system by:
$ ls -l /usr/sbin/pppd
-rwsr-xr-- 1 root dip 257720 2006-07-05 08:58 /usr/sbin/pppd
The s means "sticky" meaning only one person can use pppd at a time.
As installed, it requires Root/Adm permissions to use pppd, directly or
through front end dialer tools. This is a security precaution common to
all COMM channels. But if you want to enable a simple User to dialout,
as is basically OK for a single user PC, do:
$ su - root
# chmod a+x /usr/sbin/pppd
or for Ubuntu:
$ sudo chmod a+x /usr/sbin/pppd
after which there will be seen:
$ ls -l /usr/sbin/pppd
-rwsr-xr-x 1 root dip 257720 2006-07-05 08:58 /usr/sbin/pppd
with the last x meaning any one can execute pppd, either directly or
much more commonly through a front end dialer such as wvdial of KPPP.
Configuration file for wvdial
-------------------------------
There is a very smart dialer utility "wvdial"
which can be used once basic modem setup is accomplished. A configuration file
is needed, which begins below with [Dialer defaults]. This file can be accessed
any where by:
$ wvdial --config Path_to/configuration_file
Most commonly the configuration file is saved as:
/etc/wvdial.conf
whereat it will serve all Users of the computer. If saved as:
/home/LoginName/.wvdial.rc
it will be found and used before /etc/wvdial.conf. Note that "." beginning
a file name means "do not show it", except through usage of:
$ ls -a
Many local configuration files are thus "hidden" in your /home/LoginName/ folder
Some Linux installations have dialup tools like Kinternet, GnomePPP, and the
Redhat/Fedora Internet Connection Wizard which are front ends for wvdial and
will write /etc/wvdial.conf files. For this reason, it is advisable to test
your configuration file first, before copying it to /etc/wvdial.conf. Typically
a first test is run with:
$ sudo wvdialconf wvtest
which will search ports with names: /dev/modem /dev/ttyS* /dev/rfcomm*.
A successful ouput include a section like:
WvModem<*1>: Cannot get information for serial port.
ttySL0<*1>: ATQ0 V1 E1 -- OK
ttySL0<*1>: ATQ0 V1 E1 Z -- OK
ttySL0<*1>: ATQ0 V1 E1 S0=0 -- OK
ttySL0<*1>: ATQ0 V1 E1 S0=0 &C1 -- OK
ttySL0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 -- OK
ttySL0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK
Note: above lines are testing the driver, modem firmware is then first read by ATI
ttySL0<*1>: Modem Identifier: ATI -- SmartLink Soft Modem
ttySL0<*1>: Speed 4800: AT -- OK
ttySL0<*1>: Speed 9600: AT -- OK

ttySL0<*1>: Speed 115200: AT -- OK
ttySL0<*1>: Speed 230400: AT -- OK
ttySL0<*1>: Speed 460800: AT -- OK
ttySL0<*1>: Max speed is 460800; that should be safe.
ttySL0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK
Found a modem on /dev/ttySL0.
Modem configuration written to wvtest.
ttySL0<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
------
will be included in a successful run, where in this case /dev/ttySL0
is the responding device port. The generated wvtest file is:
[Dialer Defaults]
Modem = /dev/ttySL0
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
; Phone = <Target Phone Number>
; Username = <Your Login Name>
; Password = <Your Password>
which at a minimim must be edited to a form like:
[Dialer Defaults]
Modem = /dev/ttySL0
Baud = 115200
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
Phone = 3334445555
Username = Your_Login_Name
Password = Your_Password
Additional if your modem port is of the type /dev/pts/N , with N a number,
then there MUST be added a line:
Carrier Check = no
This requirement currently applies to dialups using the helper utility: slmodemd
together with slamr, slusb or ALSA modem drivers, OR the " " : martian_helper
used with the martian_dev for Lucent/Agere modems with DSP chipsets.
Then a test dialput can be done with:
$ sudo wvdial --config wvtest
There are some Systems for which the wvdialconf test will stall at rfcomm ports.
This is a wvdialconf bug and can be bypassed by just using wvdial with a trial
wvtest, but you need to specify the port appropriate to your modem.
If the configuration file below, lines beginning with # are comments.
Removing a # will activate a line with wvdial instructions appropriate to
special circumstances.
[Dialer defaults]
# Lines begining with # are comments.
# wvdial will look for this file at /etc/wvdial.conf or /home/LoginName/.wvdial.rc
# Redhat/Fedora have an Internet Connection Wizard in the popup menus
# ICW will write a two part /etc/wvdial.conf supporting multiple modem usage.
Modem = ModemPort
# typically a symbolic link to the true port is used, /dev/modem or /dev/ttyS*
# wvdialconf will test all port names /dev/modem and /dev/ttyS*
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
# Lack of dialtone acquisition can be due to low line voltage,
# a common problem in Italy.
# Try inserting a "dial without waiting": X3
# Init2 = ATQ0 V1 E1 S0=0 X3 &C1 &D2 +FCLASS=0
# In case of connection instabilities, specify a lower frequency:
# Init2 = ATQ0 V1 E1 S0=0 X3 &C1 &D2 +MS=34
# a MS=90 option is sometimes necessary for Internet Providers with buggy V92 protocols:
# Init2 = ATQ0 V1 E1 S0=0 X3 &C1 &D2 +MS=90
ISDN = 0
Modem Type = Analog Modem
# Dial Command = ATDP
## replaces Touch Tone prefix ATDT to Dialout_phone_number, with older Pulse prefix ATDP
Phone = Dialout_phone_number
# if going through a switch board, a perhaps necessary pause can produced with a comma:
# Phone = 1,Dialout_phone_number
Username = LoginName
# if Internet Provider is MSN.net, use under Linux: MSN/LoginName
Password = YourPassWord
# the following lines is NEEDED only for usage with slmodemd or martian_helper
Carrier check = no
# Kinternet appears to add it automatically.
## If CONNECT is achieved but browsing fails, try activating the following line
# Auto DNS = yes
## To make a logfile wvdial.out
# wvdial 2>&1 | tee wvdial.out
# # For some Internet providers, the following line is necessary
# Stupid Mode = yes
## for other wvdial options, do "man wvdial" or see the documentation in
## /usr/share/doc/wvdial/
# to dial an alternate provide use "wvdial 2nd" which will preferentially read:
[Dialer 2nd]
Phone = 2nd_phone_number
Username = 2nd_LoginName
Password = 2nd_PassWord
## End wvdial config file
This file should NOT be sent to Discuss@xxxxxxxxxxxxx
It has common guidance for modem usage after setup.
Interfererce with browser naviagation:
-------------------------------------
Other COMM channels can interfere with browsing under dialout.
Suspect channels set during your scanModem run were shown by: ifconfig
eth0 Link encap:Ethernet HWaddr 00:15:58:71:46:C7
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

UP BROADCAST MULTICAST MTU:1500 Metric:1
Interrupt:16

TX packets:18 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:1332 (1.3 KiB) TX bytes:1332 (1.3 KiB)
A block with "lo" is an internal loopback test and harmless.
However, other COMM channels such as ethernet "eth0" will block browser function
through dialout connections. Domain Name Services (DNS) needed for browsing
will be blocked by an ineffective default usage of the eth0 assigned DNS.
If is wisest to disable bootup establishment of alternate channels in your Control Center.
Depending on your Linux distribution,
one of the following root/admin commands may alternatively be effective:
# ifdown eth0
# ifconfig eth0 down
# /etc/init.d/network stop
# /etc/init.d/networking stop
Be wary that some Systems will periodically try to re-establish internet.
So if browsing should suspiciously fail, recheck with
ifconfig
---------------------------- end COMM Channels --------------------------
