The only possible errors are EABO (if the I/O time limit is
exceeded), ECIC (if you passed control to some other GPIB
device and control has not been returned to you or you have
not sent IFC* to make yourself CIC before making this call),
or EBUS (if the command bytes used for addressing cannot be
sent out). If an error occurs, the GPIB-SCSI-A aborts the
command, issues a CHECK CONDITION status response, and
sets the Sense Key to ERROR.
If Mode is 0 and there is anything in the GPIB Secondary
Address, the GPIB-SCSI-A will abort the command, issue a
CHECK CONDITION status response, and set the Sense Key
to ILLEGAL REQUEST.
The information transfer phases that the GPIB-SCSI-A drives
the SCSI through after selection are the Command, Data In,
Status, and Message In phases.
