            Only T3100 and T5100 has SW6, T1100PLUS and T1200 are
            defaulted to COM2, T1600 uses software to determine the COM
            setting, T5200 uses the SETUP program to set the COM port.

            When SW1 is set to position 2 (serial port in use), serial
            port address is used.
