本文论述了TP-86A(CPU为8086)单板机与IBM-PC或其兼容机之间在中断方式下的全双工串行异步通讯。通过这种机间通讯可以实现单板机与微机系统的资源共享,从而可大大扩展单板机的功能,提高单板机开发应用的效率;此外,当TP-86A或IBM-PC机的异步通讯接口用于实时处理系统时,本文所述的中断工作方式也具有较大的实用价值。本文所述的全部内容经较长时间的实际使用,证明可靠,实用。
This article discusses full-duplex, serial asynchronous communication in interrupt mode between the TP-86A (CPU 8086) single board microcomputer and IBM-PC or its compatible machines. This machine-to-machine communication can realize the resource sharing between the single board machine and the microcomputer system, so as to greatly extend the function of the single board machine and improve the efficiency of the single board machine development and application. In addition, when the TP-86A or the IBM-PC machine is asynchronous Communication interface for real-time processing system, the interrupt work described in this article also has great practical value. All of the contents described in this article after a longer period of actual use, proved reliable and practical.
