Hi!

Sorry about the late reply on this.
I'm afraid I'll need some more answers in near future, but for now:

Tony, do you remember / can you figure out what gsmtty GPS is on? I
never used it on that interface, and I can't seem to figure it out.

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 :)
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.

Regards,

Tony
