Abstract

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

CLC Number:

TP334.7
