| Abstract: | Considering the existence of various self-defined protocols and the complexity of protocols,by purely adopting software design method,real-time acquisition and monitoring of the data exchange and communication status is implemented.Through analyzing the mechanism of process management and serial communication procedures under Windows platform,by using software design technologies under bottom layer of the system,e.g.,process injection and API hook,etc.,the serial port exchange data are acquired in real time.The result of practical tests verifies the feasibility of this technique,and indicates the practicability of the method in mechanism analysis of communication protocols and the analysis of communication faults. |
