Yes, especially since several bugfixes were done that could help solve the problem (although not sure if they were done in 1.20 or earlier really) > > > > I have encountered an issue while running ModemManager (version 1.18.4) on > > a Cinterion PLAS8 modem.

Or are you running pppd yourself? You must ensure that MM only touches the port once pppd has exited, otherwise they'll use mismatched CLOCAL flags and MM may get a HUP when the modem got disconnected from the network (as opposed to getting a HUP only when the port goes away from the system) -- Aleksander
