CPU=x86_64,
Linux version 2.6.31-18-generic (buildd@yellow) (gcc version 4.4.1 (Ubuntu
4.4.1-4ubuntu8) ) #55-Ubuntu SMP Fri Jan 8 14:54:52 UTC 2010
scanModem update of: 2010_01_22
Presently install your Linux Distributions dkms package. It provides for
automated driver updates,
following upgrade of your kernel. For details see
http://linux.dell.com/projects.shtml#dkms
Some modem drivers can only be used in 32 bit modem on x86_64 systems,
while some others are competent on x86_64 Systems. Cases are:
1) http://linmodems.technion.ac.il/bigarch/archive-seventh/msg03119.html
for the snd-hda-intel audio+modem driver. Also applicable to AC97 modem
controllers.
In both cases, 32 bit libraries must be installed to support the slmodemd
helper having a precompiled 32 bit component.
2) For USB modems using the slusb.ko driver. 32 bit libraries must be
installed to support the slmodemd helper having a precompiled 32 bit component
3) The hsfmodem and hcfpcimodem drivers for Conexant chipsest modes are x86_64
competent.
4) agrsm packages for LSI/AgereSystems softmodems are not competent on x86_64
systems.
There are no blacklisted modem drivers in /etc/modprobe* files
Potentially useful modem drivers now loaded are:
snd_atiixp_modem snd_via82xx_modem snd_intel8x0m snd_hda_intel
Attached USB devices are:

The PCI slot 00:1b.0 of the modem card may be disabled early in
a bootup process, but then enabled later. If modem drivers load
but the modem is not responsive, read DOCs/Bootup.txt about possible fixes.
Send dmesg.txt along with ModemData.txt to discuss@xxxxxxxxxxxxx
if help is needed.
===== Advanced Linux Sound Architecture (ALSA) diagnostics =====
The ALSA packages provide audio support and also drivers for some modems.
ALSA diagnostics are written during bootup to /proc/asound/ folders.
The ALSA verion is 1.0.20
The modem cards detected by "aplay -l" are: None
The /proc/asound/pcm file reports:
-----------------------
00-00: STAC92xx Analog : STAC92xx Analog : playback 1 : capture 1
00-01: STAC92xx Digital : STAC92xx Digital : playback 1
about /proc/asound/cards:
------------------------
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xefffc000 irq 21
PCI slot 00:1b.0 has a High Definition Audio Card
The drivers are in the kernel modules tree at:
/lib/modules/2.6.31-18-generic/kernel/sound/pci/hda/snd-hda-intel.ko
/lib/modules/2.6.31-14-generic/kernel/sound/pci/hda/snd-hda-intel.ko
The modem codec file for the HDA card is: /proc/asound/card0/codec#1
--------------------------------------------------------
Codec: Conexant ID 2bfa
Address: 1
Function Id: 0x2
Vendor Id: 0x14f12bfa
Subsystem Id: 0x14f100c3
Revision Id: 0x90000
Modem Function Group: 0x2
The audio card hosts a softmodem chip: 0x14f12bfa
14f1 is the Conexant Vendor ID, and 0x14f12bfa a softmodem chipset.
Get a hsfmodem package through http://www.linuxant.com
If not a Conexant modem, the driver hsfmodem-drivers with its dependent
drivers:
----------
provide audio + modem support with the modem chip residing on the subsystem.
Any particular card can host any one of several soft modem chips.

scanModem could not identify the Support Type needed from diagnosics or
archives.
If an alternative boot into Microsoft windows can be done, do mouse
clicks on:
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.
If may contain chipset Vendor informaton.
Writing DOCs/Intel.txt
Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.4.1
and the compiler used in kernel assembly: 4.4.1
The patch utility is needed for compiling ALSA drivers, and possibly others.
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.4
linuc_headers base folder /lib/modules/2.6.31-18-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:
$ sudo dpkg -i *.deb
Checking settings of: /etc/ppp/options
asyncmap 0
noauth
crtscts
lock
hide-password
modem
proxyarp
lcp-echo-interval 30
lcp-echo-failure 4
noipx
In case of a message like:
Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
see http://linmodems.technion.ac.il/bigarch/archive-sixth/msg04656.html
For guidance on FAX usage, get from http://linmodems.technion.ac.il/packages/
get faxing.tar.gz
It has samples for a modem using port /dev/ttySL0, which must be changed to
match your modem's port.
Read Modem/DOCs/YourSystem.txt concerning other COMM channels: eth0 wlan0
wmaster0
Which can interfere with Browser naviagation.
Don't worry about the following, it is for experts should trouble shooting be
necessary.
