Query Response Generation
When the analyzer parses a query, the response to that query is placed in
the analyzer's output queue. The response should be read immediately
after the query is sent. This ensures that the response is not cleared
before it is read. The response is cleared when one of the following
message exchange conditions occurs:
• Unterminated condition—the query is not properly terminated with
an ASCII carriage return character or the GPIB END message (EOI
set true) before the response is read.
• Interrupted condition—a second program message is sent before the
response to the first is read.
• Buffer deadlock—a program message is sent that exceeds the length
of the input queue or that generates more response data than fits in
the output queue.
