Thanks for the atempt, it never made it, however...

Why? I enjoy an occasional rub...

Perhaps this is what my bbs does, MAXIMUS. I have tried to use the passed
handle with rxasync (with out calling rxasyncopen) and it failed to work.
However, I can call rxasyncopen and tell it what portname that the bbs is
on and it'll all work just fine. 

The only thing is, I have to pass portname (com1, etc...) with the call.

Ian, would it be possible to add in another function? One that would take a
hot porthandle passed from the bbs and just start using it?
