I never intend to connect directly to the machine from the module above. The module above is intended only to be a "processing center" if you will. Let's call this module above module B and the Windows machine module C.

A client, module A, connects to module B and sends a message of value "STK" to module B. Module B accepts the connection, performs pattern matching to determine what kind of message it is and passes it to the appropriate sub, and closes the socket. Then module B should go back to listening after it passes. The module B sub should connect to module C and send the message, then close the connection with C.
