Configuring the Serial Port Parameters
You use the terminal’s serial port and a communications dock, optical link adapter, or
serial interface module to transfer data in a wired network between the terminal and a
host computer, printer, or other RS-232 serial device. If your T2420 has a modem, you
can send files and data over a phone connection.
