Connecting to the Dataport Command Interface through the
RS-232 port.

The RS-232 port is a 9-pin, female, D-sub connector located on the back of the GW. The port
is configured as a DCE (Data Communications Equipment). The RS-232 port is default set to
9600 baud, 8 databits, none parity and 1 stopbit from factory. The RS-232 port is also referred
to as the Dataport.
