Interfaccia UDP
Il protocollo UDP (User Datagram Protocol) è un protocollo di trasporto sovrapposto al protocollo Internet (IP). Utilizzare l'interfaccia UDP per leggere e scrivere sia dati binari che dati ASCII. È possibile leggere e scrivere su server, computer, strumenti e utilizzare applicazioni quali streaming video e audio, sistemi POS e altre applicazioni aziendali.
