Your list seems to include almost all that should be necessary. If the PPP
link negotiation messages look okay (using the "debug" option), and there
are no other pppd error or warning messages, then the only other thing that
comes to mind is IP forwarding.
IP forwarding needs to be compiled into the kernel, and turned on at every
boot-up in a /etc/rc.d configuration file with
"echo -n 1 > /proc/sys/net/ipv4/ip_forward." The distribution kernel
probably has it compiled into the kernel, but that may depend on the
particular distribution.
If you are using the "local" option then you might want to add the
"xonxoff" option. I'm not sure that it's necessary though, using "local"
may automatically cause pppd to use XON/XOFF.
Yet another thing is speed, the pppd speed option will likely need to be
reduced from that for hardware flow control. I'd start at 9600 and work
upwards from there.
