During the course of troubleshooting communications problems, it can be very useful to see the data that is
first being transmitted to the 469 from some master device, and then see the data that the 469 transmits back
to that master device. The messages shown here should make it possible to view that data. Any of the three
communications ports may be monitored. After the communication buffers have been cleared, any data
received from the communications port being monitored will be stored in the Rx1 and Rx2 buffers with '//' act-
ing as a character break between messages. If the 469 transmits a message, it will appear in the Tx1 and Tx2
buffers. In addition to these buffers, there is a message that will indicate the status of the last received mes-
sage.
