Chipset data:

Conexant Systems, Inc. formerly Rockwell Semiconductor Systems, datasheet
PCI bus controllerless (HCF) modem
Linux support
2003-09-08: The beta program for the Rockwell/Conexant HCF modem driver is over.
The proprietary driver may be purchased from Linuxant. Old, no-cost beta versions
of the driver will not be supported or distributed by Linuxant.
Read their FAQ.

2002-03-06: There is a beta driver for Rockwell/Conexant HCF modems available here.
The beta drivers are more current than the official driver.

2002-02-06: The official Conexant driver will be posted here when it is released.

  The RC56HCF-PCI modem family is available in three forms:

  1. A single 205-pin BGA (Plastic Ball Grid Array) package.
  2. A 2-device set plug-compatible with Conexant's RS56-PCI
     host modem family. The two devices are the PCI Bus
     Interface in a 176-pin TQFP and MDP in a 144-pin TQFP.
  3. A 2-device set in a 176-pin TQFP (PCI BIF) and a 100-pin
     PQFP (MDP).

  Single device models
  RC56HCF/SP-PCI = R7156-11 (data/fax/voice/FDSP) 

  Two device models, RS56D-PCI pin compatible
  RC56HCF/SP-PCI  = 11229-14 + R6785-61 (data/fax/voice/FDSP)
  RC56HCF-PCI     = 11229-14 + R6785-62 (data/fax/voice) 

  Two device models, alternate design
  RH56D/SP-PCI    = 11229-14 + R6789-51 (data/fax/voice/FDSP)
  RH56D-PCI       = 11229-14 + R6789-52 (data/fax/voice)
