Serial over USB being spammed
When talking to the dev kit using serial over USB (via minicom in my case) the console is getting spammed by what we (@angus.ainslie and @nicole.faerber mentioned) believe may be due to ModemManager. This problem occurs with both the SIM7100 and the BM818 modules. When the dev kit automatically goes back to its lockscreen the session is logged out and sometimes minicom even loses its connection. If I stay inside Phosh and make sure it doesn't automatically go to the lockscreen (e.g. by using the touch screen every few seconds) then the console does not get this sort of spam.
