Using Virtual Pascal you could survive the port with little modifications
to the actual game if you designed your game for portability in the first
place. I.e. if you placed the comm routines separate from the rest.

There is quite a lot of info around there for programming OS/2 comm ports.
The first doc you'd want to have a look at is the SIOREF.TXT in Ray Gwinn's
SIO driver package (newest version 1.53, SIO153.ZIP). It contains
easy-to-read docs about controlling the comm port.

Basically, OS/2 comm ports are programmed as follows:
- open the comm port as a file name "COMx" (where x is the number
of the port) to obtain a handle for the comm port, or, in the case of door
games, grab the handle from the dropfile or command line and use that
- use the IOCTL interface to change the comm port settings, if necessary
- write & read stuff to/from the port
- close the comm port as an ordinary file (not necessary for door games)
