| 摘要: |
| 设计信息系统时必须解决远程终端与主机之间的通信问题，本文具体讨论以Z80 微型机系统为终端与主机 FACOM-230/38 之间的通信接口设计问题，采用的通信规程是富士通公司的 BSC 规程。文中主要讨论了接口设计应考虑的问题，规程功能分析，论证电文块长度的选择，最后分析 BSC 规程持点，并以软件实现了该规程，给出部分通信程序流程图。 |

| Abstract: |
| This report mainly discusses design problems of the interface for computer communication on the basis of the engineering task which needs to link the microcomputer Z80 and FACOM-230/38 remotely. The Fujitsu's BSC protocol is used. In this paper，the aspects in design of communication interface are discussed and some functions of the protocol are discussed，the formulas evaluating optimum length of the message block are deduced from effective line throughput，optimum division of the message block，usage of memory and so on. Finally，characteristics of the BSC protocol is analysed for communieation programming，the protocol is reali1ed by software and some communication program flow charts are presented. |
