Right. David Nugent wrote a thing called "BNU" (for BBSs, etc). It's a FOSSIL driver. In it is a set of utilities including a TSR, which, upon pressing Control-Shift-R (or somthing like that), sticks a "RING" in the port's buffer.
Install BNU and run that TSR - I'm sure this will help you out. You can also fake "NO CARRIER", "BUSY", "CONNECT xxxx", etc.

I think you would have difficulty fitting an exchange into your house, Lars. :-)
