Linux support

2003-09-08: The beta program for the Rockwell/Conexant HSF 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.

Conexant has a Beta program for HSF modems.
The beta drivers are more current than the official driver.

2002-02-06: The official Conexant driver is now available here.

Components

  The SoftK56 modem family is available in three forms:

  1. A single 144-pin thin quad flat pack (TQFP) that combines the PCI Bus
     Interface (BIF) and Line/Voice Codec (LVC). This is the lowest
     cost device option. This device set supports data/fax with optional
     TAM and speakerphone/DSVD.  (MonoPak HSF)
  2. A 2-device set plug-compatible with Conexant's RC56HCF-PCI
     host-controlled modem family. The two devices are the PCI Bus
     Interface in 176-pin TQFP and LVC in 144-pin TQFP. This device set
     supports data/fax with optional speakerphone/DSVD/TAM. 
  3. A 2-device set with a Line Codec (LC) in the smallest device
     footprint. The two devices are the PCI Bus Interface in 176-pin TQFP
     and LC in 32-pin TQFP. This device set supports data/fax with
     optional TAM only.

  Single device models
  RS56-PCI     = R6793-12 (data/fax)
  RS56-PCI     = R6793-15 (data/fax)            
  RS56-PCI     = R6793-12 (data/fax/voice)      
  RS56-PCI     = R6793-15 (data/fax/voice)
  RS56L-PCI    = R6794-14 (data/fax/voice/TAM/cellular) 
  RS56/SP-PCI  = R6793-11 (data/fax/voice/FDSP) 
  RS56/SP-PCI  = R6793-17 (data/fax/voice/FDSP)
  RS56L/SP-PCI = R6794-11 (data/fax/voice/TAM/cellular/FDSP)

  Two device models, RC56HCF-PCI pin compatible
  RS56-PCI    = 11235-14 + 20437-11 (data/fax) 
  RS56-PCI    = 11235-14 + 20437-11 (data/fax/voice)      
  RS56/SP-PCI = 11235-14 + 20410-14 (data/fax/voice/FDSP)
