摘 要:本文论述了点到点模式下,在IBM-PC机上对远端机通信请求进行中断服务的基本原理及设计方案。文章着重探讨了怎样在含有通信程序中断服务程序的常驻内存之后,其通信过程的完成便不再需要用户进行干预。因此具有显著的实际意义
Abstract: The paper has elaborated the fundamental principle and design schema of IBMPC interrupt service for remote communication request,especially described how torealize INT 21H function call in the service subprogram.As soon as the interruptservice subprogram is resident in main memory,users may no longer intervene inthe communication.
