I gave this a try with the HE910 from Telit and the following works (not =

in git format, this is just for reference... I will resubmit it later =

after comment).  Just note that it takes about 1 min for the SIM to =

reach "ready" state after power up.

This also doesn't account for QSS: 0 occurring during 'offline' state... =

need to check what happens there.

Comments?
