I think what you are looking for is the "idle-disconnect" parameter
of pppd. This parameter seems to be undocumented and sets the number
of seconds of idle time before disconneting a PPP link. By "idle-time"
it means "no IP traffic through the wire" so if you leave the
default "lcp-echo-interval" parameter set, you won't ever get
disconnected.
To activate idle-disconnection just add a line like
idle-disconnect 240
to /etc/ppp/options if you want this to be global to all PPP connections
or to /etc/ppp/options/ttyS?? if you want just certain serial ports to
be disconnected after certain time of inactivity.
I hope this is what you are looking for.
