I want to send and receive messages over tcp/ip by specifying an IP and port number and when it has send his message listen to the answer. Just like a client server program. How is the best way I realize this in PD?

cheers

Is there maybe a possibility to force netsend to send trough a certain port? Now he always takes a different one and the connected module sends back to the port where the message came from so I have to fixate the port.

ok, i was able to make a connection to my module and initialize it. But when i push a button on the module he sends a tcp message back to host. I made a netreceive object but can't catch the responded message... anyone an idea?

Is there a tutorial somewhere on how to use netsend and netreceive? i'm very new to PD and don't know how to use this features.
