VC的COM口驱动程序,使用了ACTIVEX控件

从事Profibus的开发人员可以利用改源代码理解profibus协议。添加除通讯以外的代码，很快可以开发出自己的智能节点-engaged in the development staff can use the source code to understand change Profibus agreement. Add except communications code, we will soon be able to develop their own intelligent nodes

该程序演示了如何在windows平台下使用WindowsAPI函数来操作串口，可以用以实现两台PC机之间的实时聊天。（必须连接串口电缆）-the program demonstrated how the Windows platform using Windows API function to operate serial ports, can be used to achieve between two PC real-time chat. (Must connect serial cable)

VB.net的串口通讯支持总是让人觉得有所不足，在使用VB6的MsComm32.ocx时，很多人都会在VB.net的开发中觉得很困扰。这里讲述的VB.net串口通讯类使用native代码，并且它是通API调用实现的，你会发现VB.net的串口通讯就是这么简单。 在说明如何使用这个类前，需要说明的是，本类只是一个VB.net的串口通讯演示，你可能需要根据你的情况修改后使用。-Serial Communication Programs require the support always make people feel inadequate. in the use of VB6 MsComm32.ocx, Many people will Programs require in the development feels very frustrated. Programs require here on the serial communications using native code, and it is the 14th API calls to achieve, and you will find Programs require the serial communication is as simple as that. In explaining how to use this class, there is a need to explain, this is only one type of serial communications Programs require demonstration You may need to change your position after use.

AVR单片机ATmega128的串口通讯程序，根据输入的数据，点亮不同的指示灯，可以验证串口通讯的正确性。-AVR ATmega128 serial communications procedures, data entry, lit the lights come on, can verify the correctness of serial communications.
