Hello,
i have a mc8790 and i try to enable GPS (gpsone)
is it possible to enable gps and read the position with AT commands like AT!GPSTRACK?
so gps is now working with mc8790 under linux
after downloading and installing the firmware (GPS_Enable) from Aircard890 i see the nmea channel. under linux i enable this channel and i get the correct coordinates, this is very cool 
but now umts doesn’t work 
before updating the umts channel was /dev/ttyUSB5 but now it seems that no data come in when i call the pppd command
have anyone ideas to solve this problem?
