Abstract
In order to obtain RS 232 serial communication data, the design based on AT89C51 SCM is introduced. The system used GM8123 chip expanding SCM's one serial port to three serial ports and used MAX232 chip realizing the exchange of RS 232 levels and TTL levels. The serial data was intercepted by SCM's serial port, and then SCM handled those data and sent them to the upper computer. This design has two kinds of work modes. Mode one realized real-time intercepting. Mode two used the store-and-forward principle, the interceptor can work independently.关键词
