I don't know how "nice" this binding is, but I have one with the following
spec.  Let me know if you are interested.  (Requires Win32Ada binding)

Subject: Ada95 library for Win32 serial communications?


I could have sworn that I saw an Ada library for doing serial
communications but I can't seem to find it now.  Does anybody know
where I can find a nice thick binding for serial communications for
Win32?
