Let me clarify my question. It is related to an embedded device where human interaction is not expected. If required parameter was set earlier, modem reboot shall be avoided to reduce connection setup time (or downtime) and network signalling overhead. As I understand, your suggestion above related to any external change to the modem config. because doing the change in inside a plugin would keep device in use. So, the question: is there a way to run something like "at+cfun=1,1" from some place like mm-broadband-modem-vendor.c without crashing MM? > A different approach would be to have the modem configuration change > done on boot and synchronize it so that MM doesn't start until the > configuration changes have been made. Well, this is a safest bet and a current option. Regards, Alexey
