Function Documentation

NTSTATUS cbmiec_checkcable ( PDEVICE_EXTENSION  Pdx)

Determine the type of cable (XA1541/XM1541) on the IEC bus.

This function tries to determine the type of cable with which the IEC bus is connected to the PC's parallel port. Afterwards, some variables in the device extension are initialized to reflect the type.

Parameters
PdxPointer to the device extension.
Returns
If the routine succeeds, it returns STATUS_SUCCESS. Otherwise, it returns one of the error status values.
