Bug Description

There is a race condition in modem-manager so for the Sierra MBIM modems the AT ports are not always detected. Although the modems use the MBIM protocol, having the AT ports around can be useful in case there is no equivalent MBIM command for an AT command.

See https://code.launchpad.net/~alfonsosanchezbeato/snappy-hwe-snaps/+git/modem-manager/+merge/322937 for a workaround we are using at the moment.
