大哥，你这个tcp通信的问题解决没有啊？
我现在也是用的lm3s8962的板子，开发板做client，pc做servers，我也想实现你那样的功能，您要是解决了，可以把你的工程文件发给我嘛，我参考学习下，现在调不出来，郁闷的要死，
不胜感激！！！:)

我也想做tcp作为客户端发送数据，跪谢啊！
-
检查了 ip地址没有问题的 我想做的开发板lm3s8962作为客户端，pc机作为服务器。

怎么没有我要的试验现象啊，我用的是keil4平台，测试工具上看不出数据的发送
-
什么意思啊？那个我程序里面不是有么? 我是菜鸟，你能说明白点么？
-
不好意思啊，我才搞这个，我学电气的，主任要我自己弄，我也不懂！摸不着边，所以，就把代码写上去了，谢谢你啊！
-
编译也通过啦
输入 control led on
接受区没有显示
指定本机端口1025选定时，创建会出现， 创建socket失败！ 我是新手 不知道怎么办！
希望各位大侠帮忙解决问题，谢谢
