Among them: the register address item is the initial address of the data register to be displayed.

The first data bit of [0, 0] is the number of data frames received during communication, the latter data bit is the length value of the data frame, and the data outside the square brackets is the received data frame value. This parameter is only used to monitor the normal communication status of the serial port. When the serial port communicates normally, the value of the number of received frames changes incrementally: the "frame value" changes according to the actual communication value. If these two values ​​do not change, it means that the communication port is not connected!  

The default data displayed in the pop-up initial window is: 03: Hold, and the data format is: 16 Bits Dec.
