Beschreibung
This problem is independent of devicecode as it can be reproduced with only mmcli running.
See here the EM06
- starts with no AT ports
- reboots with AT ports
- reboots again with AT ports
- reboots last time with no AT ports

Not going to make a fix for this now (in migration phase) because:
- This is not part of feature parity (EM06 was not compatible at all before)
- I do not have time nor patience for this petty device
Beitragsleitfaden
Für dieses Repository ist kein Beitragsleitfaden indexiert
Erste Schritte
- Lies das ganze Issue und danach den Beitragsleitfaden des Projekts.

- Öffne einen Pull Request, der die Issue-Nummer nennt.
Rechercherichtung
Es wird keine Quelldatei oder kein Test genannt. Beginne damit, die Sequenz mit mmcli -m und wiederholten Modem-Resets auf dem Quectel EM06-E zu reproduzieren, und verfolge anschließend, wie das Gerät nach jedem Neustart enumeriert wird. Als erledigt gilt die Aufgabe, wenn das Modem konsistent seine AT-Ports bereitstellt, statt intermittierend ohne diese zu booten.
