I might point that if I comment the "respawn" option in "/etc/init/modemmanager.conf" and then start the modem-manager binary from command-line, the broadband connection gets disconnected as soon as I exit the binary.
So, I guess the answer to my question is "no", but just want to confirm. Also, if the answer is in fact "no", is there a way to change the answer?
