无握手的异步串行通信及其在机床DNC中的应用

Asynchronous Serial Communication without Hand-shaking and its Applications in DNC of Machine Tools

本文讨论异步串行通信在实际应用中出现的一些问题，提出了既不依赖硬件握手又不依赖软件握手的通信方法，并介绍这一方法的实现以及在机床ＤＮＣ中的应用。

This paper discusses some problems arising in the practical asynchronous serial communication and pre- sents a communication method which depends nor on handshaking with hardware or handshaking with soft- ware. This method's implementation and applications in DNC of machine tools are also reported.
