ABSTRACT:
A SCSI message manipulation circuit in a SCSI expander detects a specified SCSI message from either a SCSI initiator, or a SCSI target. After detecting the specified SCSI message, the SCSI message manipulation circuit detects a pre-selected message-unit, e.g., a specific byte, within the message. Upon detecting the pre-selected message unit, the SCSI message manipulation circuit sets a pre-selected sub-unit, e.g., a bit, within the pre-selected message-unit to a state, which is programmable, as the SCSI message passes through the SCSI expander.
