A few weeks ago, Jacques and Antonio went to a lot of trouble to help me troubleshoot a modem connection with an Ubuntu 8.04 system (installed to the whole disk over Win Vista). With their help, I got that connection working for a relative of mine.
Another friend wanted me to do the same thing with his computer. My friend's machine was running XP. I checked that the modem worked (connection established, web browsing successful) under XP with the ISP that I use for testing. Then I installed Ubuntu 8.04 on the whole disk. Now I'm having problems getting this modem to connect, but the problems seem to be different than those from the prior system.
First, I ran ScanModem. From the initial output, it seemed that the IRQ was wrong, and after trying the various options, I finally got that set correctly (through the BIOS). Then I ran ScanModem again (I've run it several times further after tinkering with the problems I describe below, but there's no change to the output). Here's the ModemText output (see below the output for more description of the problem and my failed attempts to fix):

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/2.6.24-19-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

>From this output, it seemed like I needed to download the agrsm-HDA-20080721-ALSA15.tar.bz2 or agrsm-HDA-20080721.tar.bz2 files at the Linmodems site. I went to the site and found agrsm-20080808-ALSA18.tar.bz2 and also agrsm-ubuntu8.04.1-2.6.24-19-generic.tar. I downloaded both and copied and extracted them to the desktop on the Ubuntu system. I couldn't find a setup program for the first bundle of files, but I did run the setup application for the latter generic bundle of files.
I tried using the Network connection tool (the icon of two computers linked to each other at the upper right of the desktop screen) to configure the modem, trying to follow everything I learned from Jacques and Antonio previously. (I also commented out the prohibition against "password" as a password in the secrets file).
It seems that the usr/modem directory or file is missing in my system (I've looked for it and can't find it). This is the output from wvdialconf:
carl@carl-desktop:~$ sudo wvdialconf

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?
Please read the FAQ at http://open.nit.ca/wiki/?WvDial
If you still have problems, send mail to <wvdial-list@xxxxxxxxxxxx>.
Do any of you have suggestions about what I need to do?
Thank you very much!

P.S. After receiving such generous help last time, I looked for a way to donate to the Linmodems effort but couldn't find any. Do you have a mechanism for accepting donations?
