I got one response which suggested turning off timeouts. It may do the trick -- I haven't had too much time to check it out. But I have found something else. When running over an ISDN "modem", ppp is going into a tight loop after a few minutes, preventing any further packets from getting through. I am going to try to debug it tonight, but I'd be interested in knowing if anyone else has seen this and dealt with it. The fact that it is happening only over an ISDN modem, and not over a 28.8k modem, suggests that either a) it is an incompatibility with the box on the other side (an Ascend box, but apparently no one else has complained about this), or b) there is a PPP bug that manifests itself due to timing issues. Both would be surprising. Unfortunately, there is a business resting on getting this stuff working, so this is pretty high priority for me. Steven
