Along with handing all aspects of radio modulation and demodulation, the
microprocessor also maintains an extensive array of diagnostic information.
This section details the diagnostic information available, and describes how to us
the information to optimize or troubleshoot a StingRay radio network.

StingRay diagnostic information is read using AT commands, while the unit is in
the Command Mode. Refer to the section “User Serial Port Commands” to learn
how to put the StingRay modem into the Command Mode.
To see a general overview of how the modem has been operating, us the ATST
command (status request command), without any parameter. The radio modem
will respond with a list of certain operation statistics that it maintains. All statistics
start counting at 0. The ATST 1 command can be used to reset all statistics back
to 0, except the run-time timers.
Other operation and configuration statistics are available using the ATST
command, with a parameter to specify the desired statistic. The following table
