Our goal is to broaden and improve supported Linux technologies by making complete, high-quality drivers for Conexant chipsets
available to the Linux community.
Due to intellectual-property/patent issues beyond our control, the source
code of some components like modem modulations cannot be released;
however, we have attempted to reduce the inconvenience of binary-only modules
by separating the proprietary code from the operating-system specific code. The
latter is provided in source form, allowing users to install the drivers under any
supported version of the Linux kernel.
Is my device supported? Which driver(s) do I need?
Our generic Linux drivers for most Conexant HCF, HSF and DGC chipsets
support as many configurations and features as possible. However
due to the large number of modem and computer system manufacturers using
Conexant chipsets in custom products, there are no guarantees that generic drivers
will provide the same functionality as the original driver software or even work
with your modem (please see the license/legal disclaimer).
Despite this, we have many happy users!
To choose the appropriate driver(s), you must first identify your modem chipset.

Many bug fixes
We strongly recommend that all users upgrade to the latest version. Linux 2.2 kernels are no longer supported. Please switch to 2.4 or later.
Because the scope of this project has grown beyond the capacity of a single
volunteer and legal issues prevent us from using a classic open-source development model,
the HCF and HSF drivers are now available in two editions:
a free version (limited to 14.4Kbps data), available at no cost. Please use it to test if your hardware is compatible.
a full version (with 56K and FAX), available for a modest price.
The DGC driver is available at no charge. Proceeds will be used to further improve the drivers. Getting the full version is the best way to encourage us and ensure that this project continues.
If you are wondering why a Linux driver isn't already included in the price you paid for your
modem, or disagree with the practice of selling Linux software, please read this explanation.
Thank you for your support!
