echo 1 > /sys/class/gpio/gpio141/value
sleep 1
echo 0 > /sys/class/gpio/gpio141/value</pre> *Once the modem is on (led near SIM card reader, is blinking now), you can interact with it via UART 2. '''IGEP BERLIN:'''<pre>echo 0 > /sys/class/gpio/gpio145/valueecho 1 > /sys/class/gpio/gpio163/valuesleep 1echo 0 > /sys/class/gpio/gpio163/value</pre> *Once the modem is on (led near power button is blinking now), you can interact with it via UART 2. You can use Microcom to comunicate with it from the serial debug console:
