Hello,

What is the best way to program a serial port on MS-DOS in C?
For example set protocol to 9600,n,8,1,xon and output "hello world"?

Thanks for your time,
James

The best approach is to use an interrupt service routine. I've programmed several of these in the past, but I'd recommend libraries by others :-)

Greenleaf does a commercial library for this if you want to throw money around, but there are a lot of free alternatives on the net.
