Using the Serial Interface

If you have a printer, a modem, or other peripheral device with a serial interface, you can connect it to the serial (RS-232C) port on the back of the computer.

The serial port has a DB-9P connector, so be sure you have a compatible cable. To connect a serial device, follow the same steps as above for connecting a parallel device, but insert the connector into the serial port, marked with a special icon, as shown below.

Note

Additional steps may be necessary to set up the serial port so it functions properly. If you are using the port for a printer, you need to direct printer output to the serial port, not the parallel port. To do this, you can use the MS-DOS MODE or SETMODE command. See your MS-DOS manual for details.
