-------------------------- System information ----------------------------
CPU=i686,
Linux version 2.6.22-14-generic (buildd@palmer) (gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)) #1 SMP Sun Oct 14 23:05:12 GMT 2007
scanModem update of: 20071030
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. Diagnostics are under the /proc/asound/ folders.
For modems using the snd-hda-intel audio+modem driver, upgrades to
a new ALSA version are sometimes necessary to achieve function.
See for example:
http://linmodems.technion.ac.il/bigarch/archive-seventh/msg02144.html.
Audio cards with the ALC883 chipset may require an upgrade to ALSA version 1.0.15 for modem support, see
http://linmodems.technion.ac.il/bigarch/archive-seventh/msg02577.html
Copying ALSA diagnostics to Modem/ALSApault.tgz
ALSAversion = 1.0.14
Summary card and chipset information is in:
/proc/asound/cards:

The High Defintion Audio card with PCI ID 8086:27d8 may host a soft modem chip.
Bootup diagnostics lack ALSA data.
Modem not detected though HDA card diagnostics, though not excluding
a possible Conexant modem chip impervious to ALSA diagnostics.
Proceeding through alternative possibilties.
There is candidate modem software.

Softmodem codec or chipset from diagnostics:
from Archives: 10573055_Motorola_Si3054
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: slmodemd supporting the snd-hda-intel audio+modem driver
An ALSA (Advanced Linux Sound Architecture) modem driver: snd-hda-intel
provides Low Level support enabling contact with the modem hardware.
For all BUT Conexant chip soft modems (using hsfmodem software)
complementary High Level support is through a Smartlink utility: slmodemd
Download from http://linmodems.technion.ac.il/packages/smartlink/
the package SLMODEMD.gcc4.1.tar.gz having a compiled slmodemd. Unpack under Linux with:
$ tar zxf SLMODEMD.gcc4.1.tar.gz
and read instructions therein. But briefly, the modem is setup with command:
sudo slmodemd -c YOUR_COUNTRY --alsa hw:0,6
reporting dynamic creation of ports:
/dev/ttySL0 --> /dev/pts/N , with N some number
Read Smartlink.txt and Modem/YourSystem.txt for follow through guidance.
Already loaded into the kernel is snd-hda-intel and audio drivers it depends on,
displayed by: lsmod | grep snd_hda_intel

is from files:

============ end Smartlink section =====================
Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.1.3
and the compiler used in kernel assembly: 4.1.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder /lib/modules/2.6.22-14-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 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
