Programming Interrupts for DOS-Based Data Acquisition on 80x86-Based Computers
T. Hayles, David L. Potter · 1997
This application note explains how to use interrupt programming on computers based on the 80x86 family of microprocessors running the DOS operating system. This family includes the 8086, 8088, 80286, 80386, and 80486 microprocessors that are used in PC/XT/AT, EISA, and IBM PS/2 computers. This application note describes interrupts, explains how interrupts work and how they are implemented on 80x86-based computers, and discusses programming guidelines when designing an interrupt-driven DOS application. Finally, this application note contains example programming code to demonstrate how to program interrupts for a DOS-based data acquisition application.
