获取当前机器的COM口的数量，包括usb转换的串口

一个多线程串口通讯的事例,适合于在串口通信方面有基础的人进一步研究

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

这个文件夹里共3个部分，分别是串口编程与ODBC技术结合，用API函数控制串口和用MSComm控件控制串口。-This folder in a total of three parts, which are serial programming and ODBC technology, using API functions to control serial port and serial port control by MSComm control.

串口通信小程序，非常使用-small serial communication procedures, the use of very

这是我自己写的关于串口通讯的小程序,适于两台PC机之间通过(交叉串口线)串口通讯.可以(自动或手动)发送数据、接收数据、保存数据。是调试串口和初步学习串口编程的好例子。其中还用到了典型的串口类，对于从事串口编程者有一定的借鉴作用。 -that I write on small serial communication procedures, suitable for two between the PC (cross-Serial Line) serial communications. May (automatically or manually) to send data, receive data, the data is preserved. Serial debugging is a preliminary study and Serial Programming good example. It also uses the typical serial category, for those engaged in serial programming is useful role.

C51下的 485通讯程序. 包括 主机 和从机的程序. 测试通过了的-C51 under the 485 communications procedures. Including mainframe and from the plane procedures. Pass the test

setupapi方式列举本机串口，包含虚拟串口-setupapi enumerate the Serial includes Virtual Serial Port

通过PC端控制液晶显示器，解压无需密码-control through a PC-inch LCD monitor, without extracting passwords
