2 *
3 * low level stuff for Sedlbauer cards
4 * includes support for the Sedlbauer speed star (speed star II),
5 * support for the Sedlbauer speed fax+,
6 * support for the Sedlbauer ISDN-Controller PC/104 and
7 * support for the Sedlbauer speed pci
8 * derived from the original file asuscom.c from Karsten Keil

22 /* Supported cards:
23 * Card: Chip: Configuration: Comment:
24 * ---------------------------------------------------------------------
25 * Speed Card ISAC_HSCX DIP-SWITCH
26 * Speed Win ISAC_HSCX ISAPNP
27 * Speed Fax+ ISAC_ISAR ISAPNP Full analog support
28 * Speed Star ISAC_HSCX CARDMGR
29 * Speed Win2 IPAC ISAPNP
30 * ISDN PC/104 IPAC DIP-SWITCH
31 * Speed Star2 IPAC CARDMGR
32 * Speed PCI IPAC PCI PNP
33 * Speed Fax+ ISAC_ISAR PCI PNP Full analog support
34 *
35 * Important:
36 * For the sedlbauer speed fax+ to work properly you have to download
37 * the firmware onto the card.
38 * For example: hisaxctrl <DriverID> 9 ISAR.BIN
