What have you tried so far? Did you try using a ready-made communications program?

Years ago DOS allowed you to do this with communications programs called Interlink and Interserver. (Macintosh had a program called Hyperterminal).

On the occasions I have used null modem cables transfer data from one computer to the other, I usually had to put in a lot of time and effort, before I managed to get the protocols right.

It will be a big challenge for you to write your own communications program.

In C code, you essentially perform CreateFile() on a serial communication device and ReadFile() respectively WriteFle().

if you have borland turbo c. (with that blue dos screen gui), there is a sample program in its help. i cant remember the help topic but you can find out it easily.
