Set baud rate to esp8266 at 9600

I brought an esp8266-12, it works at 115200 baud rate. I sometime connect it to arduino uno to work for some projects. It would be easy if I connect esp8266 with arduino at 9600 baud rate. The AT version is 0.25. I googled and saw the AT command set documentation it had a command to set baud rate. It was like

AT+ UART_DEF=<baudrate>,<databits>,<stopbits>,<parity>,<flow control>

But the problem is I don't know what these parameters are and how to set the parameters so that is works at 9600 baud rate with arduino.

To change the baud rate of esp8266, use this command. 

AT+CIOBAUD=9600

Easy and simple. Command can be sent through serial communication from Arduino UNO.

After a long time of searching, I found the parameters to work with Arduino at 9600 baud rate.

AT+UART_DEF=9600,8,1,0,0
