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 '//
' acting 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 message.
