Bartosz: we want to try another approach to fix it. As suggested by Dan in the ML, we will try to use the primary port for connection only, and the secondary port for all AT commands. Currently I just need some free time to hack that, and after that I will push a new branch for testing.
Having such a modem for the fix development would be the best option, so if anyone is willing to send me one of those, I'll happily accept it :-)
