RS232 serial is also called COM port

RS-232 (also called serial, COM port)  is  still  common interface and most PC are still equiped with serial interface  connector. Usually it is hidden and available as internal header connector only.

There is 2 flavor of header (ex: Motherboard header) (AT/EVEREX) or (DTK/INTEL) witch match the IDC10.
You need an according port ( with the accordingly cable layout) to the flavor of header you have!
Example: If you want to have a DE-9 put on a 10pinIDC you HAVE TO put an RS-232 Port with pitch header (DTK/INTEL) or with pitch header (AT/Everex) depending of the flavour of the pinout layer!
