see this:

root@swi-mdm9x28-wp:~# microcom /dev/ttyAT
at!riowner?
!RIOWNER: 0

OK
at!riowner=1
OK

root@swi-mdm9x28-wp:~#
root@swi-mdm9x28-wp:~# echo RI > /sys/class/gpio/export
root@swi-mdm9x28-wp:~# ls /sys/class/gpio/
export        gpiochip0     gpiochip1018  gpiochip884   gpiochip980
gpio2         gpiochip1     gpiochip820   gpiochip916   unexport
gpioRI        gpiochip1012  gpiochip852   gpiochip948   v2
