AT commands port (data communication):
l
To turn the modem OFF unconditionally, use the following commands:
echo 1 > /sys/class/gpio/gpio30/value
sleep 0.5
echo 0 > /sys/class/gpio/gpio30/value
To toggle the modem power status, use the following commands:
echo 1 > /sys/class/gpio/gpio60/value

The ReliaGATE 10-05-x4 exposes the COM ports as follows:
COM port 0: /dev/ttyO4 (
l
COM port 1: /dev/ttyO3 (
l
Console port /dev/ttyO0 (

How to test a COM port

Use the utility below to test the COM port. It works in either RS-232 or RS-485 mode.
This utility allows you to transmit/receive data to/from the COM port.
NOTE: this utility does not include a local echo (it does not allow you to see the sent data)
#connect ttyO3 with a baud rate of 9600
microcom /dev/ttyO3 –s 9600
