That looks very good to me. > Before I can submit the code for review, merging the multi-sim support > (MR !330) is needed first, so any idea when it could be merged? :-) > Let's get it merged right away, we can always discuss it post-merge if anyone has comments on the new APIs implemented. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
