Editing Serial interface (section)

==IBM PC==
On PCs the serial port is also called the '''COM''' port.

Desktop PCs may still have a 9-pin RS-232 port present, if not on the back I/O panel more often as a IDC-10 socket on the motherboard for connecting to an optional I/O bracket with the DE-9 port. Note that there exist two types of wiring to IDC-10 socket: AT/Everex ("Straight Through": same numbered pin) and DTK/Intel ("Cross over")<ref name="bodenzord">Bodenzord—[http://www.bodenzord.com/archives/117 RS-232 PC Serial Port Pinout Conventions].
