具有30年传统的串行通信设备和最近涌现并发展迅速的以太网装置,这两个通信巨人之间的融合只不过是个时间早晚的问题。在1969年,Electronics Orgnnisation,即现在知名的Electronic Industries Association(美国电子工业协会,EIA),开发了RS232通信协议以标准化接口在计算机和装置之间进行数据交换的方法,这个协议已为仪表和计算机行业广泛采用为点对点的协议。 30多年过去了,由于RS232的局限性显而易 With 30 years of traditional serial communications equipment and the recent emergence and rapid development of Ethernet devices, the convergence of these two communications giants is only a matter of time. In 1969, Electronics Orgnization, now known as the Electronic Industries Association (EIA), developed an RS232 communication protocol to standardize the interface between computers and devices for data exchange. This protocol has been developed for instruments and computers Industry widely used as a point-to-point agreement. More than 30 years later, due to the limitations of RS232 is easy
