RSB-3430 Testing method;(RSB-3430 測試方法) 

 Note: RS-232: /dev/ttymxc2 
 GPIO : need to connect loopback.
 RS-485: pin1 data- & pin2 data+ (ttyUSB0)

RS-232

$ stty -F /dev/ttymxc2 -echo -onlcr 115200 crtscts
$ cat /dev/ttymxc2 &
$ echo "Serial Port Test" > /dev/ttymxc2

RS485 
    
Test RS-485 with Adam-4520.

$ stty -F /dev/ttyUSB0 115200
$ echo "Serial Test" > /dev/ttyUSB0
