Revision as of 23:55, 12 April 2006
The following modems, available in some ThinkPad models, use the Conexant HSF softmodem chip, and require an appropriate driver:
- ThinkPad 56K Modem (MDC-1.5)
- IBM Integrated 56K Modem (MDC-2)
- IBM Integrated Bluetooth III with 56K Modem (BMDC-2)
- IBM Integrated Bluetooth IV with 56K Modem (BMDC-3)
Two drivers are currently available.
Contents
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 Linuxant hsf driver
The commercial Conexant HSF driver from Linuxant supports these modem and work also on ICH6 models (e.g., ThinkPad R52, R51 and T43).
It offers free limited evaluation at 14.4kbps, and the full version costs $15.
Download: http://www.linuxant.com/drivers/hsf/full/downloads.php
This driver works well with reliable connections. It does not support voice or telephony features.
Installation
- Fedora Core: use the provided RPMs.
- 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 Suspend2
As of version 7.43.00.01, the HSF driver conflicts with Software Suspend 2. A patch is available from Linuxant.
For Fedora systems, the procedure for generating and installing a patched RPM is as follows:
# Download tarball and patches wget http://www.linuxant.com/drivers/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 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 rpm -e hsfmodem rpm -Uvh /usr/src/redhat/RPMS/i386/hsfmodem-7.43.00.01full-1.i386.rpm
