Hi,
i already fix the bug, so i think this is the real bug.
i set a callback fuc to GAtMux, and add status member for echo channel,
when i find the channel active, it will call back the fuc, fuc check all
channel is active, if all channel is active, continue to send AT
commands you want.
It is pretty hard to follow what you mean here. Can you send the actual

any questions. then we open mux, ofono will create a new IOChannel,
the previously device IOChannel should remove from main context, but
ofono don't do that. why?
I don't understand the question, sorry.
