Status (See ANSI
SCSI-2 7.3)

The status byte and status byte code are defined in Table 3.80, 3.81.
A status byte shall be sent from the target to the initiator during the
STATUS phase at the completion of each command unless the
command is terminated by one of the following events:
a) an ABORT message;
b) an ABORT TAG message; (ABORT TAG is not supported by

this scanner)

c) a BUS DEVICE RESET message;
d) a CLEAR QUEUE message;(CLEAR QUEUE is not supported

by this scanner)

e) a hard reset condition;
f) an unexpected disconnect.

The STATUS phase normally occurs at the end of a command but
in some case may occur prior to transferring the command descriptor
block.
