Dialup Modem Howto Conexant

Modems supported by the Conexant drivers

Note: Conexant does not provide drivers for Linux, but commercial Linux drivers are available from Linuxant, a separate company. Licenses cost 19.99 US dollars. (But note that full-featured versions of the drivers are also freely available from Dell.) That comes with at least one year support and kernel-version upgrades, after which you need to purchase it again if you are running a different kernel which needs a newer version of the driver (although if you have the kernel headers installed it may be able to rebuild itself for your kernel, depending on what changes have been made in the driver - just try installing the deb and see). Without the license, the drivers are limited to a maximum speed of 14.4Kbps (this restriction does not apply to the drivers supplied by Dell). However, some Conexant modems can be run with the sl-modem-drivers (smart link) or an open source driver. Note that in general, you can buy a Lucent or Intel (smartlink, or other brand with intel chipset) modem for less than 19.99 US.

Conexant drivers provided by Dell (full-speed and free)
Dell provides drivers for the Conexant modems of their Linux-based laptops which should work with almost all Conexant HSF modems [1]. These drivers can be downloaded from the following addresses:
For Ubuntu 9.04 (Jaunty Jackalope): Use this file. Unpack it and enter the resulting directory, do sudo make install and sudo /usr/sbin/hsfconfig

Note: The above didn't work for me when tested on listed-as-supported Conexant HDA modem.. See section below for instructions of installing updated alsa-drivers-linuxant + latest hsfmodem + Dell's free & full-speed binaries on Ubuntu/Jaunty 9.04 which works with HDA based Conexant Modems - jasmineaura 19/7/2009
For Ubuntu 8.10 (Intrepid Ibex): This hybrid approach has been reported to work (you can use this more recent package from Dell instead of the one mentioned in the forum post). For the lazy, just download this ready-made package; after unpacking it and entering the resulting directory, do sudo make install and sudo /usr/sbin/hsfconfig

For Ubuntu 8.04 (Hardy Heron): http://linux.dell.com/files/ubuntu/hardy/modem-drivers/hsf/.
For Ubuntu 7.10 (Gusty Gibbon): http://linux.dell.com/files/ubuntu/gutsy/modem-drivers/hsf/.
Download the .deb file there, double click it and it will be installed automatically.
Ubuntu 7.04 (Feisty) users can use this link to install their Conexant HSF driver.
