PPP servers (i.e. the program at the far end of the phone line) often
time out after a period of inactivity. This saves money if someone
has forgotten that they're dialled up (and are paying for the call),
makes it harder to hog modems, etc.
The effect the remote end closing the connection is that your pppd
gets a SIGHUP, which it correctly interprets as meaning the connection
has gone away.
