The ScsiPortReadPortBufferUchar routine transfers a given number of unsigned byte values 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.
