+port and responding to PUSH_DATA datagrams with PUSH_ACK, and to PULL_DATA 
+datagrams with PULL_ACK.
+
+Informations about the datagrams received and the answers send are display on 
+screen to help communication debugging.
+
+Packets not following the protocol detailed in the PROTOCOL.TXT document in the
+basic_pkt_fwt directory are ignored.
+
+2. Dependencies
