Com port usage
 

Hello.

I have many game machine emulators on my debian system and I enjoy them thoroughly,

I also have I sega megadrive game pad that plugs into the com port on the pc.

It would be really good if I could play the games with this pad.

I want to write or get a small program that will activate the com port so it can read the signals from the pad.

Where do I start?

Many Thanks for your help

Support for many of the old gamepads is included in the Linux kernel, and the kernel documentation shows how to wire them to the parallel port:

Even though the connector may be similar, trying to connect the gamepad directly to the serial port isn't going to work without additional circuitry.
