You could try `show mem' from a diagnostic port to see if ppp is
receiving packets and not doing anything with them. You could also
try `enable lqr'. It works in the latest ppp. If your ISP accepts
QUALPROTO requests (LQR), you can enable LQM logging to see what sort
of quality the link is (you'll need to read the rfc to understand the
numbers - sorry). If your ISP doesn't accept QUALPROTO requests,
enable LCP logging and you'll see ECHO LQRs being sent to the other
side. All [ECHO] LQRs should be replied. All duplicate [ECHO] LQRs
*MUST* be replied to - otherwise the other side is dead.
Assuming the other side is still alive, you can enable async logging
to see data being read & written to the serial device. If it's being
written and nothings being read, then your ISP needs to be involved
on the other side doing the same thing....
