[Com Port] RS232 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, now has several. But they are in the RS-232 standard based on an improved formed. Therefore, to RS-232C-oriented discussion. RS-323C standard is the United States EIA (Electronic Industry Association) and BELL and other companies in 1969 announced the development of communication protocols. It is suitable for data transfer rate in the 0 ~ 20000b/s within the scope of communication. The standard serial communication interface of the relevant issues, such as the signal line features, electrical characteristics have been clearly defined. Since the passage of equipment manufacturers have production and standard RS-232C compatible communications equipment, so that it as a standard has been in the computer communication interface is widely used.

[Com Port] Serial_Port_Communication_pdf DL : 0: RS232串口技术文摘串口硬件标准：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。串口通信软件：随着计算机应用领域的不断扩展，计算机之间的远程通信用得也越来越广泛，计算机间的远程通信所使用的通信软件，在市面上可以买到，但是通用的通信软件虽然能发送和接收文件，在许方情况下这些通信软件并不能满足实际工作的需要。本文就这一技术进行了探讨，介绍了有关的知识和技术，并由实例分步骤说明如何进行通信软件的开发。-RS232 serial port technology digest Standard serial port hardware: serial communication interface standard through the use and development, there are already several. However, RS-232 standards are based on the improved formed. Therefore, in order to discuss the main RS-232C. RS-323C standard is the U.S. EIA (Electronic Industries Alliance) and BELL and other companies announced in 1969 with the development of communication protocols. It is suitable for data rates in the 0 ~ 20000b/s within the communication. The standard serial communication interface issues, such as the signal line functions, electrical characteristics have been defined. As the production and access equipment vendors are standard RS-232C compatible communications equipment, therefore as a standard, currently in extensive use of computer communications interface. Software of Serial Communication: With the expanding field of computer applications, remote communication between the computer more and more widel
