Kirk W. and Kerry - Thanks for those suggestions. I am closer, with some additional information. It turns out that it was an illusion that I had a satisfactory connection. This new system uses an external modem on ttyS1 (com2) and it dials my ISP okay, the chat script completes okay, and then it starts PAP authentication but never brings the link up. Using "debug" in the ppp/options I get series of messages like this: sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x######> <pcomp> The seven #s are hex digits, the same for each attempt to connect, but different from one attempt to the next. Finally one last message that says: LCP: timeout sending config requests and then I am disconnected. The "pap-secrets" file is okay, and pap authentication works on other Linux systems and DOS systems with that ISP. What in hell is this all about? I am not sure where to begin to look, except I think I will fire up minicom and see what the ISP's screen looks like directly. Kerry - sorry this is an indirect reply to your message, but my addressbook is very skimpy and your message disappeared before I could reply to it. Chuck.
