摘要
介绍在便携式仪器中采用并行口实现的通讯方法。围绕并行口的数据端、状态端及控制端与单片机系统的接口电路设计，开发相应的单片机并行口通讯软件；采用ActiveX技术设计基于WINDOWS系统的并行口通讯控件。
：Communicating through parallel ports in portable instruments is introduced． It is focussing on designing circuit to operate data port．Status port and controlling port of parallel port and software for MCU is developed to meet needs of communication through parallel port． Application software based on Windows system and ActiveX will be developed too．
