queue can be monitored with the EMAV bit in the status byte register (STB). This bit is set when one or more messages is in the error message queue. This bit is cleared when the queue is empty.

Note that you must set “:ERR Verbose=1” to receive error messages. If Verbose=0 then no messages will be put into the error message queue and EMAV will remain clear.

Following is a list of possible remote error messages:
