[1] Supported baud rate range: 9600 Bps - 115200 Bps.
====UART8/RS232 initialization====
In order to use UART8 as RS232 interface, some GPIOs need to be configured as follows:
<pre>
echo 113 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio113/direction
echo 1 > /sys/class/gpio/gpio113/value
echo 136 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio136/direction
echo 1 > /sys/class/gpio/gpio136/value
echo 137 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio137/direction
echo 1 > /sys/class/gpio/gpio137/value
</pre>
====UART3/RS485 initialization====
In order to use UART3 as RS485 interface, some GPIOs need to be configured as follows:
<pre>
echo 114 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio114/direction
echo 133 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio133/direction
echo 134 > /sys/class/gpio/export
echo 1 > /sys/class/gpio/gpio114/value
</pre>
