115200 on your serial port test tool before power on. Then power on,
when the RS232 serial of product connects to serial port test tool,
the software will read out the baud rate at once. e.g.: software show
information "Baud rate: 9600", means 9600 is the current baud rate.
4) Set baud rate
For example: the current baud rate is 9600, but the baud rate of
control equipment is 19200, so the baud rate should be set as 9600.
At this time, in serial port tool, choose baud rate "9600", then input
command "set: 19200" in character format and send it out.
