====UART3/RS232 initialization [2] ====
In order to use UART3 as RS232 interface, some GPIOs need to be configured as follows:
<pre>
echo 114 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio114/direction
echo out > /sys/class/gpio/gpio134/direction
echo 1 > /sys/class/gpio/gpio134/value
</pre>
[2] RS232 configuration is available on requested Order Codes
