PAP is ok, and I tried a lot of chat-scripts meself, including scripts that
waited until the first '}' from ppp on the serverside came thru. pppd (or
the modem) disconnects me when the serverside starts ppp. My serial line is
8 bit clean; my modem works fine. I re-installed ppp, reconfigured the
kernel, updated modules,... nothing worked.
