The ScsiPortReadRegisterBufferUchar routine transfers a specified number of unsigned bytes from the HBA to a buffer.

Note  The SCSI port driver and SCSI miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
