Hello!
I'm a newcomer in Linux. I just started trying but my first experience
was frustrating because of inability to connect to Internet. I tried
to fix it myself but couldn't. Would you help me, please? I'm not able
to buy a new modem or even new computer and would not like to stop
using Linux (I've got Mandriva 2007 on my PC). Here is ModemData.txt:

CPU=i686, Mandriva Linux release 2007.0 (Official) for i586
Kernel 2.6.17-5mdv on an i686 /
Linux version 2.6.17-5mdv (rtp@xxxxxxxxxxxxxxxxxxxx) (gcc version 4.1.1 20060724 (prerelease) (4.1.1-3mdk)) #1 SMP Wed Sep 13 14:32:31 EDT 2006
scanModem update of: 2007-12-07
The modem symbolic link is /dev/modem -> ttyS0
There are no blacklisted modem drivers in /etc/modprobe* files
The Advanced Linux Sound Architecture (ALSA) packages providing audio support on your System,
also includes drivers for some modems. High Definition Audio (HDA) cards can themselves host
a softmodem chipset, with both audio+modem supported by a snd-hda-intel driver.
The ALSA diagnostics are written during bootup to /proc/asound/ folders.
Summary card and chipset information is in:
/proc/asound/cards:
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xcfe38000 irq 16
/proc/asound/pcm:
00-02: ALC880 Digital : ALC880 Digital : playback 1 : capture 1
00-01: ALC880 Analog : ALC880 Analog : capture 2
00-00: ALC880 Analog : ALC880 Analog : playback 1 : capture 2
A copy of /proc/asound had been copied to Modem/ALSAroot.tgz
PCI slot 00:1b.0 has a High Definition Audio Card
USB modem not detected by lsusb

Modem interrupt assignment and sharing:
===================================
The modem interrupt (IRQ) is 255 . IRQs of 0 or 255 are not functional!!
The CPU cannot control the modem until this situation is corrected!!
Possible corrections are:
1) Within the boot up BIOS, change from a Windows to a non-PNP/Other Operating System type.
Instructions for accessing BIOS are at:
http://linmodems.technion.ac.il/resources.html within: Additional Resourcces.
2a) Add an option "pci=routeirq" to the kernel boot up line.
Here is an example paragraph from /boot/grub/menu.lst :
title Ubuntu, kernel 2.6.15-26-686
root (hd0,6)
kernel /boot/vmlinuz-2.6.15-26-686 root=/dev/hda7 ro pci=routeirq
initrd /boot/initrd.img-2.6.15-26-686
savedefault
2b) Same as above, but use "pollirq" instead of "pci=routeirq".
3) Within some BIOS setups, IRQ assignments can be changed.
4) On non-laptop systems, moving the modem card to another slot has helped.
5) Sometimes upgrading the kernel changes IRQ assignment.

The High Defintion Audio card with PCI ID 8086:2668 may host a soft modem chip.
The NotDetermined is not supported by this kernel.
There is candidate modem software.

Softmodem codec or chipset from diagnostics:
from Archives:
Lacking a dsp (digital signal processing) chip, the modem is a software
intensive or "softmodem" type. Its primary controller manages the traffic
with the CPU. But the software needed is specified in the Subsystem.
-----------------------------------------
Support type needed or chipset:
Support can likely be achieved through two mutually exclusive alternatives:
1) The hsfmodem software for Conexant chipset modems: Read Conexant.txt
The following ALSA alternative CANNOT work with Conexant modems.
2) An ALSA modem driver plus slmodemd. Read Smartlink.txt for details, and
to test get the package SLMODEMD.gcc4.1.tar.gz from:
http://linmodems.technion.ac.il/packages/smartlink/
Writing Intel.txt
For owners of a Dell PCs with Conexant HSF modems, a driver source package with full speed enabled is available, but requires driver compiling. Read Conexant.txt

Vendor 11c1 is Lucent Technologies with modem technology now under LSI Inc.
Their Linux code developer/maintainer is Soumyendu Sarkar. Support for a chipset and its
continued maintenance is only initiated at the request of a major chipset buyer,
or comparable sponsor. Several different modem chipset types are produced:
with varying support under Linux.

Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
/dev/.udevdb
Versions adequately match for the compiler installed: 4.1.1
and the compiler used in kernel assembly: 4.1.1
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder /lib/modules/2.6.17-5mdv/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 libc6-dev (and for Debian/Ubuntu, linux-libc-dev). The also required headers of package libc6 are commonly installed by default.
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 pacakage
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
