I have Openwrt router with Arduino connected via USB FTDI adapter. Serial port is /dev/ttyUSB0 Arduino code prints some data: First part of data printed with delay via command print(), for exampl.

After reboot, we can see a new /dev/ttyUSB* device as below. This is the FTDI Serial device.

We can use this device to communicate with other serial device. Root@dragino-17be12:~# ls /dev/ttyUSB* /dev/ttyUSB0 above shows the ttyUSB0 device.

Then save the settings.

• run minicom and get the output from FTDI Serial device. Below Demo shows the output from another dragino board's UART interface.
