MSComm.output = "A Special Char. will follow: " & chr(??)

I'd also like a link to a convertion table.

However, ASCII does not define control keys like Ctrl, Alt, and Shift as far as I know.  If you need that functionality, you probably need to designate your own protocol to define how to describe these special requirements.
