The input buffer and the output queue

Input buffer

The instrument has a 200KB input buffer.
Received messages are put into this buffer and executed in order.
However, "ABORT" commands are executed immediately when received.

Output queue

The instrument has a 200KB output queue.
Response messages accumulate in this queue until read out by the controller (PC).
A query error occurs if the length of a response message exceeds 200KB.
The following events clear the output queue:
1. When the controller has read out the entire contents.
2. When power is turned off and on again.
3. Upon receipt of the next message.
