Your TransPort NX 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 TransPort NX 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.
The serial port on the rear panel is designated COMA. The COM port designation
is a conventional way to tell your software which I/O (input/output) address to use
in order to send and receive data. These I/O addresses are defined by IBM in their
Technical Reference manuals, and are understood by all popular software
manufacturers.
