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 :)

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
