Message Available
The Message Available MAV bit becomes set when any message is
ready to be transmitted over the GPlB interface (not the
-232
inter-
face). Once the message
is
sent, the MAV bit is cleared. A GPlB device
clear command will clear the output queue and, as a result, this bit.
NOTE
After a query
is
issued over the GPlB interface this bit should be checked by
means of a serial poll before attempting to read the query response.
