CPU=x86_64,
Linux version 2.6.24-16-generic (buildd@yellow) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP Thu Apr 10 12:47:45 UTC 2008
scanModem update of: 2008_08_26
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.
There are no blacklisted modem drivers in /etc/modprobe* files

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: 4.2.3
and the compiler used in kernel assembly: 4.2.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.2
linuc_headers base folder /lib/modules/2.6.24-16-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
