Kiran: I am facing problem while reading from the file descriptor I
got from modem.request(). One observation is, I get
"modem=/dev/ttyACM0 aux=/dev/ttyACM3 gps=/dev/ttyACM5" from
ofonod logs, but /dev/ttyACM5 is not accepting AT commands when I try from minicom.
Should I change gps port also to /dev/ttyACM3?
I'm not familiar with how GPS is setup on the he910. From what I
remember it is a dedicated port that is activated using $GPS* related
The port must be dedicated (so not /dev/ttyACM3) since the file
descriptor is being passed to an untrusted client.
