Hello ,
I am a beginner in using socket. I want to connect and send commmand to a module. I have it's ip adress and the port on which it is waiting for commands. Assume that String cmd is the command I want to send to the module.



But the module doesn't receive any command. Can someone help me to understand why?

ps: sorry for my english , I am french

What exactly is "a module"? Do you have code for that, too? Have you tested it running on the same machine with localhost as ip address?
 
It is sorta covered in the JavaRanch Style Guide.
