What operating system are you using? Since you say "COM1", it's
probably either DOS or Windows.

If DOS, I have no idea. If Windows, you can use my com ports package,
assuming it's ok for you to reuse stuff off the net:

But this does not "write directly to the IO port". You can't do that
in Windows!
