Windows平台和DOS环境工控机的实时网络通讯研究

针对计算机测控领域中广泛存在的Windows和DOS的网络通讯问题，提出了一种综合应用Windows Sockets和Packet Driver两种编程接口的解决方案，即Windows平台上使用Socket接口开发基于网络层的程序，DOS平台上使用Packet Driver接口进行数据链路层编程。为满足测控任务对网络通讯的实时性要求，通讯过程中使用了中断机制。最后结合实例说明了实现过程。

Research of Real-time Network Communication between Windows Platform and DOS Industrial Computer

The network communication between Windows and DOS is a widespread issue in the field of computer measurement and control. A solution which uses Socket and Packet Driver is putted forward, that is to say, the Windows platform uses Socket to develop program based on network layer and the DOS platform uses Packet Driver to develop data link layer program. The communication process also relates to interruption mechanism to meet the real-time requirement of the measurement and control task. Finally an example is given to illustrate the implementation.
