Hi,
If the aim is to have a program that actively keeps the connection
alive without sending anything, I'd advise using ``set server''
(perhaps ``set server /tmp/mysocket "" 0177'' to listen for
diagnostic connections and have a program/script that does
pppctl /tmp/mysocket set timeout 30
as setting the timeout value will also reset the idle timer.
