CPU=i686,
Linux version 2.6.22-14-generic (buildd@terranova) (gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)) #1 SMP Tue Feb 12 07:42:25 UTC 2008
scanModem update of: 2008_03_04
The modem symbolic link is /dev/modem -> ttySL0
There are no blacklisted modem drivers in /etc/modprobe* files
The Advanced Linux Sound Architecture (ALSA) packages providing audio support,
also includes drivers for some modems. The ALSA diagnostics are written during
bootup to /proc/asound/ folders.
The ALSA verion is 1.0.14
The modem cards detected by "aplay -l" are:

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
An ALSA (Advanced Linux Sound Architecture) modem driver:
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 modem:1
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.

Writing Smartlink.txt
Message http://linmodems.technion.ac.il/bigarch/archive-seventh/msg01358.html
is in part summarized below.
The snd-trident driver is not fully compatible with slmodemd support.
The may be errors written to /var/log/messages like:
codec_semaphore: semaphore is not ready [0x1][0x1300]
Check with:
$ dmesg | grep semaphore
A potential work around is to unload drivers:
# modprobe -r snd-intel8x0m
# modprobe -r snd-intel8x0
# modprobe -r snd-trident
Then reload only:
# modprobe snd-intel8x0
# modprobe snd-intel8x0m
and test the modem.
If snd-trident cannot be unloaded, it may be necessary to disable it by:
# cd /lib/modules/2.6.17-10-generic/kernel/sound/pci/trident/
# mv snd-trident.ko snd-trident.ko~
After a reboot, verify that the driver is not loaded. It should NOT be disaplayed by:
$ lsmod | grep snd-trident.
Once a success with the modem has been obtained, the setup can be made easier by
adding to /etc/modprobe.d/blacklist (or equivalent on your System)
blacklist snd_intel8x0m
blacklist snd_trident
and to /etc/modules
snd_intel8x0
snd_intel8x0m
On Ubuntu systems such edits of Root permission files can be done with:
$ sudo gedit path_to/FileName

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 package
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

To enable dialout without Root permission do:
