The following modems, available in some ThinkPad models, use the Conexant HSF softmodem chip, and require an appropriate driver:

Two drivers are currently available.

The Smartlink smlink driver

The Linux driver for Agere modems from SmartLink supports both 2.4 and 2.6 kernels. However, it does not work with the newer Intel ICH6 controllers (used, e.g., on the ThinkPad R52 and T43; trouble on the G41 has also been reported). Some users report that AT commands work but dialing does not.

The snd_intel8x0m kernel module also (incorrectly?) recognizes the BMDC-2. At least scanModem works with it. About snd_intel8x0m see MDC.

The Linuxant hsf driver

The commercial Conexant HSF driver from Linuxant supports these modem and work also on ICH6 models (e.g., ThinkPad R52, R51, T43, and Z60m).

It offers free limited evaluation at 14.4kbps, and the full version costs $19.99. The license is tied to the specific CDC modem daughter card, so if you replace your modem card you will need to buy a new license.

  • For Ubuntu, Dell released an OEM version of the linux driver (with 56K and fax support). You can download it here. Newer versions for i386 and x86_64 packaged in .tar.gz, .deb and .rpm can be found here

This driver works well with reliable connections. It does not support voice or telephony features.

Installation

  • Fedora Core: use the provided RPMs. If using a custom kernel, choose the "Generic packages with source" in the HSF downloads page.
  • Debian: run # dpkg -i hsfblablabla.deb. When asked you for the code, enter "FREE" for the 14.4kbps evaluation.
  • Gentoo: the hsfmodem package is in portage.

If you are running a 2.6.15.* kernel, you might consider running:

# hsfconfig --patch 

first, and apply the appropriate patch (there is an issue with hsfmodem and 2.6.15 tree that results in kernel oops. The patch provided by Conexant fixes that). It looks like this command has to be run in console (rather than e.g. xterm, as the menu issues some escape sequences that garble the output in xterm)

Suspend/resume

The hsfmodem driver may prevent your machine from going into suspend. If so, you may remove them prior to sleep by adding to your suspend script:

modprobe -r hsfmc97ich hsfserial hsfengine hsfosspec hsfsoar

The drivers should be automatically re-loaded upon resume by the hotplug system, if not, just manually restart hotplug or modprobe the individual drivers, adding this to your suspend script if needed.

If you use the hibernate script on Fedora Core, simple add this to /etc/hibernate/hibernate.conf:

OnSuspend 12 service hsf stop
OnResume  12 service hsf start

Problem with Software Suspend 2

Version 7.47.00.01 works fine with Software Suspend 2.

The version 7.43.00.01 of the HSF driver conflicted with Software Suspend 2. The needed patch isn't available from Linuxant anymore.

For Fedora systems, the procedure for generating and installing a patched RPM is as follows:

  • Download tarball and patches:
# wget http://www.linuxant.com/driSoftware Suspend 2vers/hsf/full/archive/hsfmodem-7.43.00.01full/hsfmodem-7.43.00.01full.tar.gz
# wget http://www.linuxant.com/drivers/hsf/full/archive/patches/hsf-7.43.00.01-suspend2.patch
# wget http://www.linuxant.com/drivers/hsf/full/archive/patches/hsf-7.43.00.01-try_to_freeze-2.patch
  • Build the RPM:
# mkdir hsf-workdir
# cd hsf-workdir
# tar xzvf ../hsfmodem-7.43.00.01full.tar.gz
# cd hsfmodem-7.43.00.01full
# patch -i ../../hsf-7.43.00.01-suspend2.patch -p1
# patch -i ../../hsf-7.43.00.01-try_to_freeze-2.patch -p1
# cd ..
# tar czvf hsfmodem-7.43.00.01full.tar.gz hsfmodem-7.43.00.01full
# rpmbuild -ta hsfmodem-7.43.00.01full.tar.gz
  • Install the RPM:
# rpm -e hsfmodem
# rpm -Uvh /usr/src/redhat/RPMS/i386/hsfmodem-7.43.00.01full-1.i386.rpm
