[ActiveX/DCOM/ATL] scom DL : 0: 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, there are already several. But they are in the RS-232 standard based on the improved formed. Therefore, to RS-232C-based discussion. RS-323C standard is the U.S. EIA (Electronic Industries Alliance) and BELL companies announced in 1969 with the development of communication protocols. It is suitable for data transmission rates in the 0 ~ 20000b/s within the scope of communication. The standard serial communications interface issues, such as the signal line feature, the electrical properties have been clearly defined. As the access equipment vendors are manufacturing and RS-232C standard compatible communications equipment, so it as a standard, currently in widespread use in computer communication interface.
