Couldn't someone build their own by just taking two computers (e.g: linux boxes or *bsd or whatever) and having them listen to the ports, then talk across the network and replicate the serial port state via IP? That's basically what the old "emulate a serial link over IP" computer games hacks use. I wonder if you could even use the same software! :) Of course this begs the question of keeping those machines up and fault tolerant, but that's left as an exercise for the reader. :) mjr. ----- Marcus J.
