TCP客户端服务器型号并行端口编程 [英] TCP client server model & parallel port programming

问题描述

我新加入了这个论坛，需要您的帮助.我正在尝试开发将在以下服务的C#代码:

1.两台PC将通过LAN连接，并且可以相互ping通(不需要任何代码，只需确保可访问性即可)
2.我浏览了几篇文章，并对如何使用TCP和套接字概念开发客户端-服务器模型有了一个粗略的认识
3.我将从客户端向服务器发送字符串"LED01 ON"
4.服务器一旦获得字符串，就会将逻辑1发送到并行端口，该并行端口将打开LED01
5.发送字符串"LED01 OFF"将执行相反的操作
6.我想为2个LED实施它

请提出建议，以便我可以轻松做到..

Hi,
I have joined in this forum newly & need your help. I am trying to develop a C# code which will serve below:

1. Two PC''s will be connected by LAN & will be able to ping each other (don''t need any code-just ensuring reach-ability)
2. I have gone through several articles & got rough idea how to develop client-server model using TCP & socket concept
3. From client i shall send string "LED01 ON" to server
4. As soon as the server will get the string, it will send logical 1 to parallel port which will turn on LED01
5. Sending string "LED01 OFF" will do the opposite
6. I want to implement it for 2 LEDs

Please suggest so that i can do it easily..

推荐答案

有关并行端口编程的示例，请参见:
未经审查的I/O端口-1-通过并行端口控制LED(发光二极管) [ ^ ]

请参阅我过去有关套接字网络设计的答案:
来自同一端口号的多个客户端 [在C#和套接字编程中使用api [如何获取keydown事件在vb.net中的不同线程上操作 [

For samples on parallel port programming, see this:

See my past Answers on socket networking designs:
Multple clients from same port Number[^],
using api in c# and socketprogramming[^].

The design of networking services and clients is tightly related to threading. Find is a useful collection of my past Answers on related topics:
