Polling Commands & Messages:
As defined above, Status-Message are sent automatically in response to Control-Write Commands, but system status may also be
determined at any time by polling, using these optional Control-Read Commands. Applications that parse and process Status-
Messages in real-time will not need these Commands, but applications can ignore Messages until periodic polling intervals, and then
issue Polling Commands to update variables and displays.
