Using the Teseo-Suite, the Host can send the commands and check the Teseo III message responses.
The first field in the $PSTMLOGQUERY is a bitmap which specifies:
•2b00: No more data, and the data in the message is invalid
•2b01: more data available, and the data in the message is valid
•2b11: No more data available, and the data in the message is valid
