Yep, I agree.

Just wanted to understand whether 'a data connection started in PDP context 1' (by the ATD) is the same as 'PDP context 1 being activated' (indicated by the AT+CGACT), or is one a subset/follow-on of the other. _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
