摘要
本文先对微机并行口在SPP协议与PS/2协议下的功能特点及打印机的工作原理进行了简单的介绍,并在此基础上详细叙述了在PS/2协议下微机并行口通讯在炼钢自动化控制系统改造中的实际应用,以便为其它领域的并行口编程提供参考。
The article describes some features about computer parallel port under SPP protocol and PS/2 protocol and the theory of printer generally, and then explains an application of computer parallel port communication under PS/2 protocol in updating steel-making automation system in detail. It provides reference for programming the parallel port in other fields probably.
