Message Queues Introduction to Programming
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition 21
The Output Queue
The output queue contains responses to query messages. The instrument
transmits any data from the output queue when a controller addresses the
instrument as a talker.
Each response message ends with a carriage return (CR, 0D
16
) and a LF
(0A
16
), with EOI=TRUE. If no query is received, or if the query has an error,
the output queue remains empty.
The Message Available bit (MAV, bit 4) is set in the Status Byte register
whenever there is data in the output queue.
