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.
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. 11235-14 PCI Bus Interface 176-pin TQFP 20437-11 Line Codec 32-pin TQFP 20410-14 Line Voice Codec 144-pin TQFP 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)
