SIGHUP makes pppd think that carrier has gone away. There's no point
in trying to close LCP when that happens; the serial port is just
closed (causing DTR to drop and the modem to go offline) and the IP
interface is torn down.

So, yes, try this. If it doesn't do exactly that, then let us know
about the bug ...
