I'm running pppd 2.4.4b1 and I specify "modem" as an option but when
carrier drops, pppd seems to hang around for an idle time before giving
up. I'd kind of expected that when using a modem, it'd monitor CD and
give up when it dropped. (Not that I can find anything in the
documentation to support that.) Am I off base in my expectation?
(That is, wouldn't that be reasonable behavior, even if it isn't what
pppd does now.)
