gts
(continued)
Before performing a
gts
with a shadow handshake, you
should call EOS to establish the proper End-Of-String
character or to disable the EOS detection if the End-Of-String
character used by the Talker is not known.
If you call
gts
and the GPIB-SCSI-A is not Controller-In-
Charge (CIC), the GPIB-SCSI-A records the ECIC error,
issues a CHECK CONDITION status response, and sets the
Sense Key to ERROR.
The information transfer phases that the GPIB-SCSI-A drives
the SCSI through after selection are the Command, Status, and
Message In phases.

Example 2 contains the entire program sequence.
