Help with sending commands across a network

[jduncanator]

Hi

I need some help with a program I am writing. What I need to be able to do is send a command across a specific network port (eg. 2124) to a specific ip address. I already have writen the recieving code (for the iPhone os) and accepts commands like:

filefound("Name of file",filetype,size)

All this is to be sent in plain text and once received the iPhone will then send a command like:

nextfile()

I really need some help here. Thanks in advance

If someone even knows how to send a file across tcp it would be a great help.
