I've got a TCP socket in which I listen for data send from a device. This
works, but when I connect to that socket connection with
"net.createConnection" (from another part of the code) the incoming data
does not get send BACK to the device.
Does anyone know why the data is not send back to the device? I checked
with wireshark, the data is not send. It works when I send data from within
the socket connection (not from the "createConnection" part)

Yes, the incoming data is "logged" with console.log, it is sock.write()
that is not working.
