It doesn't or at least not on my system. Despite having:
- cabled the modem correctly,
- enabled rts/cts (at&c1&d2) on the modem
- disabled the clocal flag (in fact I'm using the rc.serial script from
/usr/src/etc applying first the default and
then the modem function for every modem line)
- using the modem parameter with pppd
the daemon isn't killed when the line drops.
Did I miss something or is the modem parameter "not fully implemented"
(see pppd man page) the culprit?
