串行通信接口标准经过使用和发展，目前已经有几种。但都是在RS-232标准的基础上 经过改进而形成的。所以，以RS-232C为主来讨论。RS-323C 标准是美国EIA(电子工业联合 会）与BELL等公司一起开发的1969 年公布的通信协议。它适合于数据传输速率在0～ 20000b/s 范围内的通信。这个标准对串行通信接口的有关问题，如信号线功能、电器特性 都作了明确规定。由于通行设备厂商都生产与RS-232C制式兼容的通信设备，因此，它作为 一种标准，目前已在微机通信接口中广泛采用。-Serial communication interface standard through the use and development, now has several. However, in the RS-232 standard on the basis of an improved formed. So to the main RS-232C for discussion. RS-323C standard is the United States EIA (Electronics Industry Association) and BELL, such as the development of the company in 1969 with the publication of the communication protocol. It is suitable for data transfer rate at 0 ~ 20000b/s within the scope of communication. The standard serial communication interface of the relevant issues, such as signal line features, electrical characteristics have been clearly defined. Because of prevailing production and equipment manufacturers have standard RS-232C compatible communications equipment, t

RS232串口,详细编程源代码,包括串口的设置,读写.-RS232 serial ports, a detailed programming source code, including the serial port settings, reading and writing.

这是一个很实用的串口通信例子，是基于LabVIEW编写的，希望能对大家有所帮助，谢谢！-This is a very practical example of serial communication is based on LabVIEW prepared, I hope everyone can help, thank you!

本源码采用spcomm串口控件，接受数据采用线程方式，这是一个串口测试工具，可以用来做串口监听等。非常适合使用delphi开发串口程序的程序员做参考！-the source used spcomm Serial Control and accept data using threads, it is a serial testing tools can be used to do Serial wiretapping. Delphi is very suitable for the development of Serial procedures programmers refer!
