GT-I9100

Setup: Replicant 6.0 0004 RC3

To get the modem UART:

First get root in the device.

root@i9300:/ # echo MODEM > /sys/devices/virtual/sec/switch/usb_sel

Then unplug and replug the USB cable.

Then some /dev/ttyACM* device appear on your laptop when you plug it again.

$ ls -la /dev/ttyACM*
