HSF (softmodem) driver

This package contains Linux drivers for the Conexant (formerly Rockwell) HSF Softmodem family.

The drivers should work on most current Linux distributions, with the 2.4 or 2.6 kernels. A Pentium processor with the MMX enhancements is required. Some systems may require kernel recompilation with special ACPI patches, especially with 2.4 kernels. Using a 2.6 kernel is recommended.

The following modem devices are recognized by the driver:

  • MC97 modems from other manufacturers may appear under the AC-Link Controller PCI IDs above, but this driver only supports Conexant devices.

    Many vendors (such as Dell, HP, IBM, U.S. Robotics/3Com, etc..) have shipped modems based on Conexant modem chipsets. If you have a modem based on the HSF chipset but with different PCI vendor or device IDs, please contact If supported, your device could be added to the list and automatically recognized in future versions of this driver.

    See the INSTALL file for installation instructions.

    The modem AT command set is described in the file 100498D_RM_HxF_Released.pdf.

    Bug reports are welcome. (see section "REPORTING PROBLEMS" in INSTALL file)
