External Printer
Your TREK 2 computer is equipped with an enhanced bi-directional parallel port.
Use the parallel port to connect the computer to a printer or plotter. The parallel
port is the most widely used interface on personal computers because it usually
does not require setup commands or special configurations on either the
computer or the peripheral device. After you connect a peripheral device to a
parallel port, secure the two small screws on the connector.
Serial Devices
The rear panel of the TREK 2 computer has a standard RS-232C serial interface
port. Use the serial port to connect a peripheral device that can both input data to
the computer and receive data from the computer. Serial ports are widely used on
everything from mainframe computers to display terminals and modems.
