NdisRawReadPortUchar reads a byte from a given I/O port on the NIC.
void NdisRawReadPortUchar( Port, Data );
Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.
Pointer to a caller-supplied variable in which this function returns a byte read in from the port.
NdisRawReadPortUchar runs fast because it need not map a bus-relative I/O port address onto a host-dependent logical port address at every call.
