| Abstract: | This paper analyzes the mechanism and flow of USB CDC Class and implements the virtual serial port.It also proposes the method of implementing modbus communication protocol through the virtual serial port.The USB driver of operating system,the debugging and application software based on serial port still are available.and avoiding the trouble of developing software.This method provides one simple means of communication for the industrial control network. |
