They aren't used dynamically though are they? The protocol itself takes care of flow.
I'm unable to have a real m100 talk via serial with VT. That seems odd. Must be a hardware pin issue. Interestingly the same hardware works if VT is swapped for teraterm. So I guess that virtualT must be flowing off while teraterm is flowing on....
