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.

  R6793-11 RS56/SP-PCI     combined BIF and LVC  144-pin TQFP
  R6793-12 RS56-PCI        combined BIF and LC   144-pin TQFP
  R6793-15 RS56-PCI        combined BIF and LC   144-pin TQFP
  R6793-17 RS56/SP-PCI     combined BIF and LVC  144-pin TQFP
  R6793-21 RS56/SP-PCI11P1
  R6794-11 RS56L/SP-PCI    combined BIF and LVC  144-pin TQFP
  R6794-14 RS56L-PCI       combined BIF and LC   144-pin TQFP

  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)

Have you practice a litle love today? To your loved ones perhaps? Your parrents, your spouse, your children, your neighbours, or even your enemy? Here is a short tip on how to love them - Love is patient, love is kind. It is not jealous, is not pompous, it is not inflated, it is not rude, it does not seek its own interests, it is not quick-tempered, it does not brood over injury, it does not rejoice over wrongdoing but rejoices with the truth. It bears all things, believes all things, hopes all things, endures all things. So these three remain ... faith, hope, and love; but the greatest of these is love.
