-                       Devices are waiting for GVCP packets listening to the GVCP port (3946). When the 
client sends a command GVCP packet to the device, the device sends back an acknowledge packets in return. 
Each command/acknowledge pair is identified by a 16 bit value, which allows to check if an acknowledge packet 
corresponds to the previsoulsy sent command. 0 is an error value for this identifier. If an acknowledge is 
not received after a given timeout period, another command packet is sent, until a maximum number of retries 
is reached.
