This is not in any of the Rockwell data sheets I have; they all say they reset and won't answer w/o DTR on AT&D3. Do you have a model number? I suspect your modem cable or your port setup in rc.serial. The only real problem I am aware of with Rockwell chipsets is that they cause US Robotics Sportster Faxmodems to lock up when you call one (bet that was an engineering nightmare to get that to happen 8-)). > > If the machine crashes, getty goes away (the POST state on a proper serial > > port is to not assert DTR), and so the modems are not answered. > > If the machine deadlocks, gettys won't go away.
