NOTE
If the serial line baud rate is set to Automatic, the transmitter attempts to
determine the baud rate of the traffic in the RS-485 network. The
transmitter cycles through all baud rate choices, listening for 10 seconds
at each rate. When it detects valid RS-485 traffic, it remains at the
detected baud rate until it is reset or power cycled.
