I have heard stories of people with Telebit TrailBlazers who have picked up a phone on the same line as the modem, while it was on line. They heard a lot of screaching, but the modem didn't miss a beat. For those not familiar with TrailBlazers, they talk some kind of packetized, error-corrected, protocol between themselves, and have the ability to adapt to amazingly bad phone lines. I wouldn't be surprised if some of the new MNP level-whatever or V.32 modems would be similarly resistant to loosing a connection just because sombody picked up a phone on the line.
