One of these, and you could message people, or transfer programs. But, I don't have one, so I can't test my program. If anyone has 2 DOS computers and one of these, message me.
I did try it and it works. I still have the com-link cable but only dos on 1 pc. I'd suggest you'd try a crosslink cable for network, mucho faster btw.

PS if you'd like, I could set up my winxp machine as a dos station and then I can try for ya. Let me know.
