The so-called communication protocol refers to an agreement between the two sides of communication. The agreement includes uniform rules for data format, synchronization mode, transmission speed, transmission step, check and error correction method, and control character definition, and the two parties ...
调制解调器连接:在互联网和网络连接不普及的时代,RS-232常用于通过调制解调器(modem)连接计算机与电话线网络,实现拨号上网。 串行控制台:在一些工业控制系统和网络设备中,RS-232用于远程访问控制台,进行配置和故障排除。 数据采集:在一些科学仪器和数据采集系统中,RS-232用于将数据从设备传输到计算机进行分析。 串行打...
An infrared RS 232 communication link protocol is particularly suited for correcting any errors introduced during a transmission of information. The information is transmitted from a transmitting station (Figure 6) to a receiving station (Figure 7). Each of the stations has a control counter (310)...
The general communication protocol only conforms to several layers of the OSI 7 model, such as the EIA - rs-232 - C: the physical layer. IBM's SDLC (synchronous data link control protocol) : data link layer. ANSI's ADCCP (advanced data communication protocol) : data link layer IBM's ...
