A settable redial timer helps to avoid the problem where both ends
of a link want to dial at the same time and the line winds up busy
for both ends. The process id is logged in /var/run/PPP.system where
system is the name of the called system. When both ends of a link
are running in demand dial mode, you need an easy way to get the pid
of the ppp on the called end so it can be killed and re-started with
-direct or pppd started to handle the incoming ppp session.
2. Add secret description for "set timeout" to man.
