More on modem problems. I have verified that the modem works properly from Dial Configuration, using the DEBUG option. In fact, if I do not close Debug window, then the connection stays up and I can use the internet.
However if I close the DEBUG window, and try to use rp3 via RH Dialup, rp3 fails saying the interface is inaccessable. However it does spawn pppd before failing, and multiple attempts will start multiple pppd's.
Also, the pppd spawned by DEBUG and by Dial Config have different arguments! But one works and the other doesn't. If there are any rp3 gurus out there, I'd appreciate some thoughs. Almost debugged....
