Title:
Could not grab port (tty/ttyS4): 'Cannot add port 'tty/ttyS4',
unhandled serial type'
Status in modemmanager package in Ubuntu:
Confirmed
Bug description:
I see these warnings in the journalctl after every boot, on Ubuntu
15.10:
```
Dec 11 09:18:08 M2 ModemManager[816]: <warn> Could not grab port
(tty/ttyS4): 'Cannot add port 'tty/ttyS4', unhandled serial type'
Dec 11 09:18:08 M2 ModemManager[816]: <warn> Couldn't create modem for
device at '/sys/devices/pci0000:00/0000:00:16.3': Failed to find primary AT port
Dec 11 09:18:08 M2 ModemManager[816]: <warn> Modem couldn't be initialized:

Any clues what this could be and why modem can't be initialized?
