If I remember correctlly, the virtual modem works by taking the phone-number, convert to an IP-address, and then uses TELNET to connect to the other machine.

See if there is something in the README file, or the Wiki in my signature.

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

In that case you'll need directserial.
You could try my new patch.
DirectSerial patch
(scroll down)

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

Thanks

The latest patch is for Linux too, you'll have to apply it and recompile Dosbox.

you mean Nullmodem.diff?

Does it have docs on how to use it?

Thanks

Compile or run it? The latter:
In the dosbox.conf under [serialport] write

serial1=directserial realport:ttyS0
or
serial1=directserial realport:ttyUSB0
(or ttyS1 ...)
The Dosbox com1 will be forwarded to the real interface.

I put the patchfile in /dosbox-0.65 then did:
patch -p0 <nullmodem7.diff and it said the following:

Perhaps you used the wrong -p or --strip option?

Then I did configure and then make and make died with the following:

serialport.cpp: In static member function `static bool CSerial::getBituSubstring
(const char*, Bitu*, CommandLine*)':
serialport.cpp:1072: error: invalid conversion from `const char*' to `char*'

make[4]: *** [serialport.o] Error 1

There were also a ton of warnings before this.

What did I do wrong??

Thanks

PS, Sorry to be such a pain. 😀

It's a patch vs CVS, not the 0.65 release.

http://sourceforge.net/cvs/?group_id=52551

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