I installed a modem that has some chance of being supported. At first it
wanted IRQ 255 but I solved that by disabling PnP in the bios. Now it
looks promising but there seems to be some question about Mars and the
2.6.22 kernel. The patch from Brad House seems to involve compiling
which I'd hoped to avoid!

They will know your Country's modem code, which may be essential for
dialup service.

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 /proc/asound/ audio+modem diagostics are being copied.
Finished copy to Modem/ALSAroot.tgz
The ALSA verion is 1.0.14
The modem cards detected by "aplay -l" are:

----------------end Softmodem section --------------
The modem has a Lucent/Agere/LSI Mars or Apollo DSP (digital signal
processing) chipset.
Support packages for 2.6.n kernels are at:
http://linmodems.technion.ac.il/linmodems/ltmodem/kernel-2.6/martian/ ,
with current update martian-full-20071011.tar.gz
See AgereDSP.txt for Details.
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
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
