Yes, it has been done, at least with a PC as a router (based on KA9Q). We have done a demo of it right here on our campus. The ISDN packet driver used in this demo was developed at the University of Michigan. I don't know what its status is - it hasn't been contributed to the public packet driver collection. This one doesn't do anything about dropping the phone call when the line is idle and redialing when it's back, but that could be added, I'm sure. Doug Nelson Michigan State University
