摘要: 不同于PC机串行通讯端口RS-232-C的常规标准, 利用异步串行通讯端口的控制端(DSR)直接接收串行数字信号.用此方法成功地实现个人计算机直接接收无线寻呼中文信息.这种方法简单、可靠,可用于研制无线寻呼信号实时监测系统,还可用于接收并研究未知格式的串行数字信息.

Abstract: Unlike the ordinary standard on serial communication of PC,the control port(DSR)of RS-232-C is used to receive serial digital signals directly.In this way the PC is able to receive the information in Chinese from the pager.This simple and reliable method can be applied to the development of real time monitor systems for pager signals,as well as the reception and research of serial digital signals of unknown format.

Key words: EIA standard, serial communication, radio paging, monitor
