4.2 Port 2

Port 2 becomes valid only by setting it first ON. Setting can be done from the programming
menu. Port2 RS-232 / RS-422 are selectable, but TTL and LVTTL are hardware related and fixed
at the factory. Only one port can be ON at a time (Port 1 or Port 2). Note that when the
programming mode (pin 12 connected to ground), is selected the modem will automatically use
Port 1 settings (COM1, 9600 bps, 8-bit data, none parity, 1 stop bit).
