摘　　要：主要描述工业控制领域中最通用的数据交换接口RS-232口的通信原理及接口定义。介绍RS-232通信过程中采用的两种基本校验方法如累加校验和CRC校验的实现方法,并对后台多线程形式的通信方法进行描述。还给出Windows下采用Delphi编程工具进行串口通信编程的编程方法和通信流程。Mainly describes the field of industrial control in the most common data exchange interface RS-232 port communication principle and interface definition. Introduces the RS-232 commu- nication process using two basic calibration methods such as accumulative check and CRC calibration method, and describes the background thread forms of communication method. Also gives serial communication programming programming method and its communication process by usin~ Delphi pro^ramminz tool under Windows.
