I would like to play multiplayer games over 2 PCs by directly connecting them together via their modems using a telephone wire. I have successfully transferred files using Bitware and the modem strings ATX0D on the dialling modem and ATA on the answering. However I have not been able to make the modems talk to each other within a game. I think the problem lies in the answering modem since I was able to make a connection when I dialled within the game on one machine and used Bitware on the other to answer.
I want to do this as I have a long telephone wire but no null-modem cable.
