I got the program going and it's working great, Thanks you for all your patience and help. 😀

I put the patchfile in /dosbox-0.65 then did: patch -p0

you mean Nullmodem.diff? Does it have docs on how to use it? Thanks

All I could find was stuff for windows, I need this for linux. Thanks

Nah, that won't work, I have to dial up several other modem connections with this software. It's a control type software that requires dialup connections. Thanks

Is there a way to connect to a modem in dosbox under linux? After searching this site I have noticed mention of a virtual modem but no documentation on how to get htere or how to use it. I have a program that works great under dosbox but I have to be able to connect through the modem. Any help …
