Mechanism Research of Serial Port Communication in Basis and Relevant Realization

Wang Yi

Open publisher page 3 citations

Abstract

In general,the serial communication in the application interface is usually regarded the port devices as files,and realized the communication by CreateFile mode.This paper analyzes the serial control chip of INS 8250 and interrupt control chip of Intel 8259,configuring the registers,writing or reading in the relevant address,it realizes the function of installation,initialization,communication and uninstall of serial port,
