* '''Acquisition of equipment information'''<br>
<br>
In Windows 7, we can check whether the serial port connection is normal and the device number of the serial port through the device manager. If the device is not recognized normally, please check whether the driver is successfully installed. If there is a problem with the driver installation, you can try to use 360 Driver Master to scan and install the driver.

* '''Putty configuration'''<br>
<br>
Set the serial port to the corresponding port number (COM4), disable flow control, and set the speed to 115200
