/* Supported cards:
* Card: Chip: Configuration: Comment:
* ---------------------------------------------------------------------
* Speed Card ISAC_HSCX DIP-SWITCH
* Speed Win ISAC_HSCX ISAPNP
* Speed Fax+ ISAC_ISAR ISAPNP Full analog support
* Speed Star ISAC_HSCX CARDMGR
* Speed Win2 IPAC ISAPNP
* ISDN PC/104 IPAC DIP-SWITCH
* Speed Star2 IPAC CARDMGR
* Speed PCI IPAC PCI PNP
* Speed Fax+ ISAC_ISAR PCI PNP Full analog support

* Important:
* For the sedlbauer speed fax+ to work properly you have to download
* the firmware onto the card.
* For example: hisaxctrl <DriverID> 9 ISAR.BIN
