摘要
介绍了无线数传模块SA68D11的RS232通讯协议,详细说明了Delphi的ActiveX通讯组件Spcomm的属性、方法、事件。通过实例对利用Spcomm通讯组件进行SA68D11串口通讯的设计方法进行了详细讨论,并最终实现了Win9x环境下PC与无线数传模块SA68D11的串口通讯控制。
This paper introduces the RS232 communication protocol of wireless data transmission module SA68D11 and elaborates the property,method and event of Spcomm ——the ActiveX communication component of Delphi.The author discusses in detail the designing method of programming SA68D11 serial communication with Spcomm through an example,and finally realizes the serial communication control between PC and SA68D11 under Win9x.
