I think it can still be problem if modem disappears while we dont send
anything. E.g. we can be waiting for another call.
I think the most clean solution is to use netlink or libudev. Udev can notice
device removal/new devices - we can use the same trick. While the device is
removed we can suspend sending AT commands and when it's added we can resume.
Anyway for now I have this ugly patch . It seems to work quite nice and i'd
wait if we get answer from Option and then we can replace it with something
nicer or completely remove it.
