摘　　要：串行通信作为计算机通信方式之一,主要起到主机与外设以及主机之间的数据传输作用,串行通信具有传输线少、成本低的特点,主要适用于近距离的人-机交换、实时监控等系统通信工作当中,借助于现有的电话网也能实现远距离传输,因此在串行通信接口是计算机系统当中的常用接口。主要在介绍串行通信概况的基础上,介绍串行通信口技术的发展及应用情况。Serial communications as one of computer communications ways, primarily as the host and peripheral data transfer between the host and the role of serial communication with a transmission line of small, low cost features, mainly for short range of people - machine exchange , real-time monitoring system communication work, by existing telephone network long- distance transmission can be achieved, so the serial communication interface is common among computer systems interface. This paper Based on describes the serial communications in the profile, introduction of serial communication port develop- ment and application of technology.

关 键 词：串行通信 通信接口 电平转换
