Interface Table
IFTYPE - Interface card type
Specified in TTGEN through the interface definition (the keyword MUX) with the following results:
IFTYPE | = ZCOM_ITYPE_Z7200A(6) | - Z7200A | ACC | |
IFTYPE | = ZCOM_ITYPE_Z7350A(7) | - Z7350A | ACC | |
IFTYPE | = ZCOM_ITYPE_Z7400A(8) | - Z7400A EISA | ACC | |
IFTYPE | = ZCOM_ITYPE_Z7300A(9) | - Z7300A | ACC | |
IFTYPE | = ZCOM_ITYPE_Z7340A(11) | - Z7340A PCI | ACC | |
This field allows for the future support of extra interface types.
IFSTAT - interface card status
This word indicates the current status of the Mux card. It is updated by the driver. Bit 15 indicates whether the card is usable (when set) or not (when cleared).
