No, that's confusing, and it is /not/ what the current code does.

I think it should be, for Windows:

  127.127.20.0 => invalid

  127.127.20.1  => COM1

  127.127.20.4  => COM4

perhaps:
  127.127.20.256 => sorry, COM256 not supported

and that is what the current code does.

If your C code (I don't find C easy to read) achieves that, fine.

Cheers,
David
