I'm trying to find out whether Network Manager enables my built-in 3G modem when it's used or if it is enabled at boot. As my netbook has no LED for the 3G I have to find out another way.

One possible way would be to see what AT commands Network Manager send to the modem when connecting. How do I do that? I've checked /var/log/messages and /var/log/daemon.log but they don't seem to contain any AT commands. Any ideas?

I'm on Jaunty Netbook Remix, if that matters.
