 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 
definition (id: modem, value: cards.pcm.modem)
error: alsa setup: cannot open playback device 'modem:1': Invalid argument
error: cannot setup device `modem:1'
R40:/home/ellsworth# modprobe -r snd-intel8x0m
R40:/home/ellsworth# modprobe snd-intel8x0m
R40:/home/ellsworth# cat /proc/asound/pcm
00-00: Intel ICH - Modem : Intel 82801DB-ICH4 Modem - Modem : playback 1 :

R40:/home/ellsworth# slmodemd --alsa -c b5 modem:1

error: alsa setup: cannot open playback device 'modem:1': Invalid argument
error: cannot setup device `modem:1'
R40:/home/ellsworth#

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

Packages needed for support of Advanced Linux Sound Architecture (ALSA) 
support should be installed: alsa-base and alsa-utilities!!
They are necessary for support of ALSA modem drivers, many Conexant chipset 
modems and success of modem diagnostics for modems requiring slmodemd 
actions.

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.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
 Read DOCs/Smartlink.txt and Modem/DOCs/YourSystem.txt for follow through 
guidance.

 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


Checking pppd properties:
	-rwsr-xr--  1 root dip 265880 2005-03-24 14:21 /usr/sbin/pppd

In case of an "error 17" "serial loopback" problem, see:
    http://linmodems.technion.ac.il/linmodems/archive-sixth/msg02637.html

To enable dialout without Root permission do:
	$ su - root  (not for Ubuntu)
         chmod a+x /usr/sbin/pppd
or under Ubuntu related Linuxes
	 chmod a+x /usr/sbin/pppd

Checking settings of:	/etc/ppp/options
asyncmap 0
auth
crtscts
lock
hide-password
modem
proxyarp
lcp-echo-interval 30
lcp-echo-failure 4
noipx

In case of a message like:
   Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
see http://linmodems.technion.ac.il/bigarch/archive-sixth/msg04656.html

Read Modem/DOCs/YourSystem.txt concerning other COMM channels: eth0 eth1 eth2 
sit0
Which can interfere with Browser naviagation.

 Don't worry about the following, it is for experts should trouble shooting be 
necessary.
