Issue created Oct 01, 2020 by Guido Gunther@guido.gunther💤Owner

Dialing with bad reception

under bad reception MM eventually discards the modem completely:

Okt 01 17:39:34 pureos ModemManager[507]: <error> [modem0] port ttyUSB1 timed out 10 consecutive times, marking modem as invalid

Signal strength icon then disappears from the shell and only a killswitch off/on brings it back. I wonder if the modem firmware crashes here. (i had seen this before but could now gather logs)
