This unfortunately will also persist if the user sells the modem to someone else unfortunately, which seems a bit broken, I wonder if AT&F1 is better if MM provides some sort of user hook to add extra config. BTW AT&F1 doesn't erase the custom configuration profiles, it just doesn't use them. Apart from this ATZ vs AT&F1 issue, just running which ever one is chose once on port open, not after every call would fix the hot-swap issue. What are your thoughts on that? > Are you testing MM with a TTY exposing multiple virtual channels via > CMUX already? How's your setup? I have been (using an small standalone program to set up CMUX, and then running MM against the virtual channel ttys without any knowledge of the parent/master tty). It sort of works, but I have been having a few issues - one with call hangup (although I think now that this is probably due to MM not issuing AT&D2 or similar before trying the DTR hangup method), and the other is down to an apparent deadlock when the tty gets passed to pppd. I'm seeing this deadlock in CMUX mode on a Beaglebone (armhf), and also in "normal" mode on (i.e. no CMUX) on the Beaglebone. I'm not seeing the deadlock on amd64 in non-CMUX mode, but I haven't got to the bottom of things yet...
