A few years ago I tried to get this working (see archives for Red Hat
2.4.20-20.9 on IBM R40 with Agere softmoden) but the Agere driver once
available through IBM gave flaky performance. I've been using a PCMCIA modem,
but it recently got fried by a campus phone system so I'm back to looking at
the internal modem. This time I'm using Debian Sarge, but hope to upgrade
when Lenny goes stable.
I ran scanmodem, then followed the directions to download
SLMODEMD.gcc3.3.tar.gz, then followed the directions found there to install
the ALSA packages, then do:
R40:/home/ellsworth# cp slmodemd /usr/sbin
R40:/home/ellsworth# modprobe snd-intel8x0m
At the next steps I got errors:
R40:/home/ellsworth# slmodemd --alsa -c b5 modem:1
error: mixer setup: attach hw:1 error: No such file or directory
ALSA lib pcm.c:1947:(snd_pcm_open_conf) Invalid type for PCM modem:1

I'm getting in over my head again. Advice?

Packages needed for support of Advanced Linux Sound Architecture (ALSA)

They are necessary for support of ALSA modem drivers, many Conexant chipset
modems and success of modem diagnostics for modems requiring slmodemd
actions.

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.gcc3.3.tar.gz having a compiled slmodemd. Unpack under
Linux with:
$ tar zxf SLMODEMD.gcc3.3.tar.gz
and read instructions therein. But briefly, the modem is setup with command:
slmodemd -c YOUR_COUNTRY --alsa modem:1
reporting dynamic creation of ports:
/dev/ttySL0 --> /dev/pts/N , with N some number

Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udevdb
Versions adequately match for the compiler installed: 3.3.5
and the compiler used in kernel assembly: 3.3.5
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 3.3
linuc_headers base folder /lib/modules/2.6.8-2-686/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.
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.
kernel-kbuild is installed
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
