利用系统热键可以方便用户的操作，比如经常使用的Alt + Tab可以快速切换窗口；Crtl + Alt + Delete键可以调出Windows任务管理器或重启机器；oicq软件也会注册系统热键方便用户的操作，等等。本程序就注册一个系统热键Alt + Z，在应用程序执行的任何时候只要按下该热键就会弹出一个消息对话框。 (system hotkeys can use user-friendly operation, For example, the regular use of the Alt-Tab window can quickly switch; Crtl-Alt-Delete keys could be released Windows Task Manager or the reopening of machinery; oicq software registration system hotkeys will be user-friendly operation, and so on. The procedure for registering a system hotkeys Alt Z, Application procedures for the implementation of any time by pressing the hotkey will pop up a message box.)

XMODEM 是一种适合在两个计算机之间进行文件传输的简单协议。嵌入式系统调试环境经常利用此协议或其变体，通过UART 端口进行image 的下载。实践者通过此实验环节可对通信协议的基本要素有较深入的了解，同时对通信协议在实时操作系统环境下的实现方式有初步了解。(XMODEM is a fit between the two computers Simple File Transfer Protocol. Debugging embedded systems often use this protocol environment or its variants, through the UART port for image downloading. Practice through this experiment, could be on the basic elements of communication protocols have a better understanding of communication protocols at the same time in real-time operating system environment to achieve a preliminary understanding of the way.)
