摘　　要：DOS系统由于技术成熟等优点在嵌入式操作系统领域始终占据着重要的地位,因此大部分的嵌入式计算机的程序设计都是在DOS平台上完成的.介绍了如何通过直接对INS8250的内部寄存器操作来实现串行通讯,以及多串口通讯在DOS平台上的中断服务函数的程序设计,并解决了多串口通讯的高号中断问题.For one of virtues is the mature technique, the DOS system takes an important place in the embedded operation system all the time. So design for most of the embedded computer programs are completed on the DOS platform. How to implement the multi-serial communication in the way of operating directly INS8250＇ s register and the program design of IRQ function on the DOS platform are introduced. And the issue of high-order IRQ in the multi-serial communication is resolved.

关 键 词：多串口 串行通讯 中断
