Using The Serial Interface - Epson 10020 User Manual

Using the Serial Interface

If you have a printer, modem, mouse, or any other peripheral
with a serial interface, you can connect it to the serial
(RS-232C) port on the back of the computer. The Apex uses a
25-pin male connector, so be sure you have the proper cable. If
you are not sure, check with the store where you bought the
computer and printer.
To connect a serial device, follow the same steps outlined
above for a parallel device, but connect the cable to the serial
port.
Setting up the serial port for a printer
If you are using a serial printer but your software does not
support a serial printer, you must do two things before you can
use the serial printer:
Set up the data transmission parameters for the port
Tell the computer to redirect printer data from the parallel
port to the serial port.
