Interesting... I now wonder how we can setup all this to work automatically, if at all possible. We don't have any carrier-specific customization right now anywhere. Maybe some user specified parameter asking for a specific type of PDU to generate? -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
