一个以位图切换技术实现波形实时显示的程序

此代码为简单的ftp服务器，里面有课程设计相关内容，适合在校大学生学习和使用-This code for a simple ftp server, which has curriculum design-related content, suitable for college students to learn and use

设置端口名，波特率，打开端口，就可以发送数据，同时可以收到数据，还可以选择发送的方式，比如，可以以十六进制方式发送，在DATA中会显示数据部分，即是除去帧头和校验位之后的数据部分，

用以太网与plc 通信的一个例子 可以参考-with Ethernet and Communications plc example of a reference

用c＋＋builder做的，用于模拟can主控节点和分节点通讯的例子-using c++ builder done for the simulation can control nodes and communications nodes at the example

基于OpenH323的一个VoIP程序，下载自国外专业网站-based on OpenH323 of a VoIP procedures downloaded from the website abroad

手机串口通信帮助文件档，可以看看，不过是Delphi方面的，如果你不是学习Delphi的请不用下载！-Mobile phone Serial Communication Help file file, you can look at, but aspects of Delphi, Delphi learn if you are not please do not download!

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.
