Hi!
quoted
My notes say:

/dev/motmdm1 -- basic support, calls, on/off                                    
/dev/motmdm3 -- send sms interface                                              
/dev/motmdm9 -- receive sms interface                                           

(and gsmtty numbering is same)
Yes I have not had a chance to look at these for several months now,
but have the latest set in droid4-pending-v5.10 branch in my github
tree.

The gnss device is at /dev/gsmtty6, see the current droid4-agps tool
to upload the almanac also on github. That's has turned out to be a
pretty good gsm serdev test too :)
Thanks a lot for the info! Is it this one?
https://github.com/tmlind/droid4-agps . GPS worked for me even w/o
AGPS support, but I broke even that, so I need to fix that first.

For now I converted gnss driver to use serdev interface, and n_gsm to
provide it... Not yet finished but I believe I'm walking in the right
direction.
Great, sounds good to me if you got things working with just serdev
calls :) I'll try to take a look at this stuff again after I have
the other pending droid4 issues out of the way like v5.12 charger
and keyboard stuff.
Just ask for latest code :-). I still believe I'm going right
direction, but now I understand why you did it the way you did. Sound
code needs to listen on gsmtty1, with the data still being provided
for userspace.

Best regards,
								Pavel
