No idea about packet data for now.

I already tried to nudge Pavel to propose something. ? I believe that kernel doing the multiplexing and "normal" /dev/gnss0 being available to userspace is actually very nice solution. > >Oh, I think I forgot to answer your question regarding PM, > >there's nothing that the user space needs to except to avoid > >polling the /dev/motmdm* devices unnecessarily.

So in > effect you're integrating power management with the telephony stack. I don't understand. Display power management should be separate from ofono? Tony: are there expected to be differences between motmdm1 and other ttys? It does not gatchat seems to work ok with ttyUSB4, but does not quite behave with motmdm1. Are the settings like ctsrts and baudrates used for something? Plus, it seems has its own subsystem, so this is needed: + udev_enumerate_add_match_subsystem(enumerate, "motmdm"); Best regards, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
