| 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. and researches the mechanism of serial port communication in basis. |
