Re: [hylafax-users] Adaptive Answer and Mgetty Issues

[George Bell <gbell5@xxxxxxx>]

I have experienced this problem too.  To get an authoritative answer on
this it is probably best to ask on the mgetty list, although I'd hate to
tell them that I'm using hylafax to launch mgetty ;).  My guess is that
the -r option (same as the "direct y" configuration in mgetty.config)
which allows mgetty to answer on an already opened line is also causing
it to ignore carrier detect.  So if for some reason the connection drops
ungracefully during the session mgetty won't know about it and keep
running on the tty.   One possible solution to this is if all you need
is to establish ppp sessions you can start pppd directly from hylafax
without going through mgetty first.

What's this?  I thought we fixed this.
