Let me preface my answers with:

1)  My main server is still running F10
2)  I haven't had to use dialup for 8+ years now

Probably in earlier fedora releases.  I'm not sure about now.

NetworkMangler should work with any device that it can control.  I'm not
sure how it controls serial dialup.

Back in the day, I installed a daemon called diald (dial-deamon).  Its
sole purpose was to sit in the background and wait for traffic being
sent to ppp0, then check to see it the interface was up, if not, it
would dial the connection to your ISP for you (seamlessly).  If you were
lucky, your connection attempt wouldn't time out before your link came
up and all would be well.  It would shut it down after a predetermined
period of in-activity.  Kinda like NetworkManager wants to do today.

I just checked, and the same RPM as I have installed is still available
on SourceForge:   diald-1.0-1.i386.rpm

I suspect that you might have to do a little work to make a x86_64
version....  And you might have to do something to NetworkMangler to
keep it from getting in the way.

Not that I'm aware of, but, pppd is a dinosaur these days with Wi-Fi,
DSL, Hi-speed Cable modems, etc  and may be "forgotten".

In my Gnome session, I can go to System->Administration->Network and
create a new Network connection.  One of the selections is "Modem".
Perhaps this is the way to go?  If you create it, will NetworkMangler
see it?
