Hi sam

I use an ActiveX control to do serial comm on VC++6. This control is
called CommX and is from GreenLeaf Software. It basically does the
hardware handling on the PC and gives You methods, properties and
events instead.

For a free alternative check out

http://codeproject.com/system/cserialport.asp

which is a MFC class to wrap access to the Win32 APIs dealing with
serial ports. I havn't tried this myself, though.

I have also been told that in the free software section at
www.taltech.com there should be a C/C++ code example of a terminal
program. Have not checked this myself either.


Regards Ruben
