Between links on Unix, third-party serial port devices under
Windows which might not use the COMx convention, and other such
variations, I'd strongly recommend you *not* try to use an
index origin of 0 but instead pass the open() routine (or
whatever you have) a *string* naming the serial port.

By the way, does your win32 implementation work well with
threads, if one thread is trying to read from the port while
the other is trying to write to it?
