How can I send non-ASCII characters like Ctrl-S to the serial communication port?

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

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

Thanks

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.

Ctrl-S, also know as DC3 or XOFF, is Chr$(19).

Ctrl A to Ctrl Z are used as chr(1) to chr(26)
