以前分析串口通讯用Device Monitoring Studio或SUDT，后来的usbxpress没有虚拟串口了，因此写了一个SiUSBXp.dll，来拦截软件的调用和返回数据，还挺管用的。能找出通讯的内容和过程。需要的可以联系jvd@163.com-Previous analysis of serial communication with the Device Monitoring Studio or SUDT, later usbxpress no virtual serial port, so write a SiUSBXp.dll, to intercept calls and return the software data, kinda workable. Be able to identify the content and process of communication. Need to contact jvd@163.com
