    Would tend to depend on the operating system.

    how about Win 2000 or NT, it's written under NT but is supposed to run under 2000.

    You can use the CreateFile() API function, (don't worry about the name), to get a handle to a com port. Look in the help for that function with particular regard to the "Communications resources" section.

    Once you have a handle you can use any of the handle based I/O API functions to read/write/control the port. That's how I would do it.
