RING SYSTEM
The MTX ring uses channel A of the dart. If the ring is installed, the baud command must not be
used for either channel as the dart is initialised differently for the ring. Channel B is not used by the
ring and is available as serial I/O port. Node commands are provided to set the baud rate and data
format for channel B.
