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

串口通讯在客户端/服务器类型的应用程序设计中经常要使用到，目前串口通讯采用的一般是专用软件包或者标准串口通讯协议(如XMODEM、ZMODEM等)，这样完整详细且免费的软件包比较少，所以在SPCOMM的基础之上建立了本文所描述的串口通讯协议，称之为RCC(表示为Reliable Comm Communication)，其主要目标是在用串口进行通讯的客户端/服务器双方建立一条可靠的通讯链路，就象TCP(RFC793)一样。该协议的目前的开发是采用VC++，应用平台为WIN95/NT，但作为RCC协议的本身不受具体编程语言及操作系统所限制-Serial port communication in client/server type of application design often use to the current serial communication is generally used in special packages or a standard serial communication protocols (such as XMODEM, ZMODEM, etc.), such a complete package details and free more less so on the basis of established SPCOMM described in this article serial communication protocol, called RCC (expressed as a Reliable Comm Communication), whose main objective is to communicate with the serial port client/server sides to establish a reliable communication link, like TCP (RFC793) the same. The current development of the protocol is used VC++, application platform for WIN95/NT, but as the agreement itself, RCC concrete programming

串口控制程序一般分为查询和中断两者方式。查询方式适用于简单的应用，简单可靠，但是缺点是需要占用处理器资源，在发送或者接收数据的时候不能做其它的事情，处理器利用率低。中断方式下，在发送或者接受数据的时候处理器还可以做其它的工作，效率较高。-Serial control procedures will generally be divided into two way query and interruption. Query applied to simple applications, simple and reliable, but the drawback is the need to occupy processor resources to send or receive data at the time should not make other things, the processor utilization rate. Interrupt mode, the send or accept data when the processor can do other work, more efficient.
