When writing frequency, the computer prompts "Initialize serial port errors! Local communication"

The causes of errors may be: 1. Software use errors, 2. Written terminals are in a state of booting? 3. Does the writing frequency be the original factory standard writing frequency? 4. If the USB interface is connected to the computer, is it installed? Is the 5 port selection correct? Excluding the above reasons, please send the maintenance station or Ke Li for detection.
