ok. GPIO (INT) seems to work as output.

Code:
echo 67 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio67/direction
# changing direction will set output to low
echo 0 > /sys/class/gpio/gpio67/value
echo 1 > /sys/class/gpio/gpio67/value
Picture below is from making pulse from command line
echo 1 > value ; echo 0 > value


and the other one is from setting it back to input, it goes "slowly" up as it is pulled high with pull-up resistor.
echo in > direction
