Two steps trigger, with timeout. In case one
fails, modem will not power up.

what is this for? It is not a good idea.

Why do you bother renaming this. Stick with mux_init_timeout.

I really thought that we cleared on how to do this. This is utterly
complex and unneeded.

So GAtChat has a builtin queue. And new commands will only be send after
the other has been processed. You can easily cancel pending commands
from a callback these days.

So you can just call g_at_chat_send() three times initially and then be
done with it. If any of these fail, you just cancel all pending commands
and fail the init. That simple.

There is no need for this complexity at all. Please re-work this patch
as I described in the other review. It should be a really simple patch
actually.

Regards

Marcel
