This tutorial shows how to send and receive data using RS232 interface on StarSBC-6ULL with communication extension board. The default Yocto image build according the tutorial [[VisionSOM_imx-meta-somlabs-hardknott]] contains all required software tools.

=== Loop test ===

The extension board has two RS232 interfaces available so they may be connected to perform the test in a loop. All signals are available on the J101 and J201 connectors. They should be connected according to the following table:

{| class="wikitable"
|-
! RS232-1 signal
! RS232-2 signal
|-
| RS232-1 TXD (J101 pin 3)
| RS232-2 RXD (J201 pin 8)
|-
| RS232-1 RXD (J101 pin 4)
| RS232-2 TXD (J201 pin 7)
|-
| RS232-1 CTS (J101 pin 1)
| RS232-2 RTS (J201 pin 10)
|-
| RS232-1 RTS (J101 pin 2)
| RS232-2 CTS (J201 pin 9)
|}

Both interfaces are already defined in the default module device-tree and are recognized as /dev/ttymxc2 and /dev/ttymxc6 devices. The device files may be used directly for reading and writing and the bitrate may be set using the stty tool:

<pre>
root@starsbc-6ull:~# stty -F /dev/ttymxc2 9600 crtscts
root@starsbc-6ull:~# stty -F /dev/ttymxc6 9600 crtscts
root@starsbc-6ull:~# cat /dev/ttymxc2 &
[1] 465
root@starsbc-6ull:~# echo "123" > /dev/ttymxc6
123
</pre>
