PC to PC via Serial to GamePort

Is there a converter or way to connect a PC to another PC and have PC #1 be a joystick for PC #2? This is a special project and must have the gameport side be the recieving end.

For a better example...

PC #1 can send data via serial port to some kind of converter that changes the digital data into analog resistance to simulate a common joystick or gamepad that would be plugged into the gameport on PC #2.

I haven't found anything on the internet that could do this, but I know it can be logically done, I just don't know how.
