I'm afraid a lot of the work I've done to date is proprietary and can't
be shared, but I have posted some items to this and the MM list.  However,
I'm happy to talk through specifics, especially since I think that would be to
my benefit and everyone else's.

However, in short, the monitoring is on the modem devices and ModemManager
state and kind of went from there.

I did propose some removal of PPP options during compilation, since this
was a very real and serious problem for us, however it seems that needs
some extra refinement, since it's still not 100%.
