Hi!
I have a Motorola modem:
Ven 8086, Dev 24C6, Rev 03
Following instructions from ModemData.txt doesn't work:
(on vanilla 2.6.23.1)

Kernel
Linux version 2.6.23.1 (root@averamihel) (gcc version 4.1.1 20070105 (Red Hat 4.1.1-51)) #6 Thu Oct 18 12:05:33 MSD 2007

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 = 1.0.14rc1
USB modem not detected.
Modem or candidate host audio card have firmware information and diagnostics:

The PCI slot 00:1f.6 of the modem card may be disabled early in
a bootup process, but then enabled later. If modem drivers load
but the modem is not responsive, read Bootup.txt about possible fixes.
Send dmesg.txt along with ModemData.txt to discuss@xxxxxxxxxxxxx
if help is needed.

New Case Only
-------------------------------------------
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: slmodemd
An ALSA (Advanced Linux Sound Architecture) modem driver: snd-intel8x0m
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.gcc4.1.tar.gz having a compiled slmodemd. Unpack under Linux with:
$ tar zxf SLMODEMD.gcc4.1.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 Smartlink.txt and Modem/YourSystem.txt for follow through guidance.
Already loaded into the kernel is snd-intel8x0m and audio drivers it depends on,

============ end Smartlink section =====================
Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.1.1
and the compiler used in kernel assembly: 4.1.1
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder /lib/modules/2.6.23.1/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.
Compressed files at: /usr/src/linux-2.6.23.1.tar.bz2
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.
