DOS: Send a Message to a Listening Port via MATLAB

I am running win7. Not a "pure" mathlab question, but I hope someone can help.

I have a third party application running on my machine. It is listening on port X for the message "STOP", which will cause the 3rd party app to shut down.

I wish to use system.m to pass this message to the app. How can I do this? I suspect this requires knowing the correct command line inputs.

thank you

telnet via system.m

That will not work by itself. In order to get that to work, you would need to use some mex code that did a process open of telnet: otherwise you will not be able to connect to the input of the telnet process.

There are several TCP/IP communication programs in the FEX: FEX: Search TCPIP. This is not the system command, but they can send a message to a specific port.
