So if I understand correctly, you are saying that once the powered=3Doff re=
quest =

has been sent down to the modem, no other requests are valid.  In other wor=
ds, =

oFono's current implementation does not remove the atoms until powered=3Dof=
f =

request succeeds (which might result in those atoms attempting operations), =

which is wrong.

Right?

We reply with the busy error, you're correct.  However, I don't really see =

anything better we can do here, do you have any suggestions?
