Asynchronous communication control adapter 异步通信控制适配器
This paper analyses the development destination of the token ring network environment based on RS-232 asynchronous communication adapter, discusses the design and implementation of its four layers protocols and introduces the implementation process of sharing printing of the application layer as an example. 本文分析了以RS-232异步通讯卡为基础的令牌环网的网络环境开发目标,对其四层协议的设计与实现进行了讨论,并以应用层的共享打印为例介绍了实现过程。
This paper introduced a basic constitution of multiple asynchronous serial communication interface adapter and option of the multiple input/ output channel. 简要介绍了多路异步串行通讯卡的基本构成,然后着重介绍了如何选择输入和输出的通道。
