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.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。该文档是对RS232C标准的详解.-serial communication interface standards through the use and development of that there are already several, but they are in the RS-232 standard on the basis of improved form of. RS-323C standard of the United States EIA (Electronic Industry Association) BELL companies together in 1969 to develop the communication protocol. It is suitable for data transfer rate of 0 ~ 20000b/s within the scope of communication. The document on the understanding the standard RS232C.
