RS232 serial port debugging tools

    压缩包有六个文件，分别是绘制圆波导TE波和TM波各模式的横截面场分布、三维静态场分布、三维动态演示。能够绘制的模式有TE波或TM波01-23共2*9种。除截面场分布文件是运行程序后自动生成9种模式分布图外，其余文件是运行后根据提示输入参数（如绘TE11就找到对应的文件，由提示输入1，1即可），参数是模式下标。圆波导模多存在极化兼并，图中可以看出，但是只绘制了余弦情况下对应的场分布（正弦只是旋转了90度）。压缩包里有程序运行的部分结果。时间仓促，结果没来得及仔细核对，有错误希望指出。

虽然Windows下可视化开发工具如VC、Delphi、C＋＋ Builder等都有专用的定时器控件Timer，而且使用很方便，可以实现一定的定时功能，但最小计时精度仅为55ms，且定时器消息在多任务操作系统中的优先级很低，不能得到及时响应，往往不能满足实时控制环境下的应用。不过Microsoft公司在Win32 API函数库中已经为用户提供了一组用于高精度计时的底层函数，如果用户使用得当，计时精度可到1ms。这个计时精度、对于一般的实时系统控制完全可以满足要求。现将由C＋＋ Builder 4.0提供的重新封装后的一组与时间相关的主要接口函数（函数名、参数、功能与Win32 API基本相同）说明如下： -visual development tools such as Visual C++, Delphi, C++ Builder and others all have dedicated Timer timer control, but it is convenient. can achieve a timing function, but only the minimum time of 55 ms accuracy. Timer news and multi-task operating system in the low priority that is not to respond in a timely manner, often fail to meet the real-time control environment applications. However, Microsoft Corporation in the Win32 API function has been to provide the user with a group for high-precision the bottom was a time function, if the user is properly utilized, time accuracy can be a ms. Accuracy this time, and for most of the real-time control system can meet the requirements.
