Hello!
I have a Dell Latitude d430, and have been trying to get its modem
working using
ALSA drivers from debian packages, but with no success.
Any help will be appreciated.

CPU=i686, Debian GNU/Linux lenny/sid
Linux version 2.6.22-2-686 (Debian 2.6.22-4) (waldi@xxxxxxxxxx) (gcc

scanModem update of: 20071018
The modem symbolic link is /dev/modem -> ttySL0
There are no blacklisted modem drivers in /etc/modprobe* files
Potentially useful modem drivers now loaded are:
snd_intel8x0m
Advanced Linux Sound Architecture (ALSA) spackage providing audio support
on your System, also includes drivers for some modems. For modems using the
snd-hda-intel audio+modem driver, upgrades to a new ALSA version are sometimes
necessary to achieve function. See for example:
http://linmodems.technion.ac.il/bigarch/archive-seventh/msg02144.html
Copying ALSA diagnostics to Modem/ALSAroot.tgz
ALSAversion = 1.0.14

Modem or candidate host audio card have firmware information and diagnostics:

The High Defintion Audio card with PCI ID 8086:27d8 may host a soft
modem chip.
Bootup diagnostics lack ALSA data.
Modem not detected though HDA card diagnostics, though not excluding
a possible Conexant modem chip impervious to ALSA diagnostics.
Proceeding through alternative possibilties.
There is candidate modem software.

Softmodem codec or chipset from diagnostics:
from Archives:
Lacking a dsp (digital signal processing) chip, the modem is a software
intensive or "softmodem" type. Its primary controller manages the traffic
with the CPU. But the software needed is specified in the Subsystem.
-----------------------------------------
Support type needed or chipset:
Support can likely be achieved through two mutually exclusive alternatives:
1) The hsfmodem software for Conexant chipset modems: Read Conexant.txt
The following ALSA alternative CANNOT work with Conexant modems.
2) An ALSA modem driver plus slmodemd. Read Smartlink.txt for details, and
to test get the package SLMODEMD.gcc4.1.tar.gz from:
http://linmodems.technion.ac.il/packages/smartlink/

Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
The kernel was compiled with gcc version 4.1.3 and a compiler is not installed
linux-headers-2.6.22-2-686 resources needed for compiling are not
manifestly ready!
If compiling is necessary packages must be installed, providing:
gcc-4.1 linux-headers-2.6.22-2-686
For Debian and some related distributions, a package
kernel-kbuild-2.6-22 may be needed to support driver compiling
If a driver compilation files with message including some lack of some
FileName.h (stdio.h for example.
Some additional kernel-header files need installation to /usr/include.
For Debian/Ubuntu related distributions, run the following command to
display the needed package list:
$ sudo apt-get -s install linux-kernel-devel
While some of the files may be on the install CD, others may have to
be found through http://packages.ubuntu.com
For Ubuntu Feisty, additional packages required were:
libc6-dev linux-libc-dev
available through http://packages.ubuntu.com/ , if not on the install CD.
Such packages may have different names for other Linux distributions.
Try installing just the libc6-dev, then test the compile again.
