英语翻译
当今社会人与人之间的交流,是通过交换信息来完成的.处于两个不同的城市或更远地方的人们进行信息交流时,所用手段是书信或电话等.从广义上讲,用任何方法通过任何媒体将信息从一个地方传送到另一个地方均可称为通信.然而,在微机系统中,微处理器的这种神通广大的功能必须通过外部设备才能实现,而外设与微处理器之间的信息交换及通信又是靠接口来实现的,所以,接口技术已成为直接影响微机系统的功能和微机应用推广的关键.RS-232标准最初是远程通信连接数据终端设备DTE(Data Terminal Equipment)与数据通信设备DCE（Data Communication Equipment)而制定的.因此这个标准的制定,并未考虑计算机系统的应用要求.但目前它又广泛地被借来用于计算机（更准确的说,是计算机接口）与终端或外设之间的近端连接标准.

Exchanges between people in society today, is accomplished through the exchange of information. Are two different people in the city or further afield when the exchange of information, the use of means of correspondence or telephone. Broadly speaking, by any means through any medium of information transfer from one place to another can be called communication. However, in the computer system, microprocessor functions of this magic and must be achieved through an external device, while the peripheral and the exchange of information between the microprocessor and the communication is realized by interface, so interface technology has become a direct impact on the functions of computer systems and computer applications to promote the key. RS-232 standard was first remote communication links data terminal equipment DTE (Data Terminal Equipment) and data communications equipment DCE (Data Communication Equipment) and developed. Therefore, the development of this standard does not consider the application of computer systems requirements. But it has been widely borrowed for the computer (more precisely, a computer interface) and between the proximal end or peripheral connection standard.
Key words: communication; computer interface; RS-232; data terminal equipment
