How do I open COM1 for read.write access in C

[tstone]

My computer is running Windows XP and I have the Visual C++ Express
Edition compiler. I need to write a program that drives an ASCII
device via the COM1 port. I'm having trouble locating documentation
on the proper syntax for opening the COM port device and registering
for interrupts from the Com port so that I can handle the I/O on a
character by character basis (required for the hardware that will be
attached).

Can anyone supply links to the appropriate documentation?

Thanks

Tom

You ask in a group dealing with programming in C.
