So, reading the tcp packet, parsing data, sending to the serial thread and also 
sending tcp reply and closing connection is done in tcp_thread (by callbacks)? 
This looks ok for me, because all pcb manipulations will be done in tcp_thread 
context. How can I use tcpip_callback function? Can you show me a short example?
