u = udp(___,Name,Value) creates a UDP object and specifies additional options with one or more name-value pair arguments. If you specify an invalid property name or property value, the object is not created. Connect the UDP object to the host. fopen(u) Write to the host, and then read from the host. fwrite(u,65:74) A = fread(u,10)

TCP connect scan is the default TCP scan type when SYN scan is not an option. This is the case when a user does not have raw packet privileges or is scanning IPv6 networks. Instead of writing raw packets as most other scan types do, Nmap asks the underlying operating system to establish a connection with the target machine and port by issuing TCP and UDP Ports Explained - BleepingComputer If it uses the UDP protocol to send and receive data, it will use a UDP port. Figure 1, below, is a represenation of an IP address split into its many TCP and UDP ports. UDP Scan (-sU) | Nmap Network Scanning

UDP. UDP is an unacknowledged mode protocol, meaning that there is no active mechanism to retransmit data that has been lost during the exchange. As such, you might think that UDP would be a bad way to send and receive data compared to TCP — and you’d be right if you were sending an email, viewing a webpage or downloading a file.

UDP¶. The purpose of example application below is to demonstrate UDP communication between ESP8266 and an external client. The application (performing the role of a server) is checking inside the loop() for an UDP packet to arrive. When a valid packet is received, an acknowledge packet is sent back to the client to the same port it has been sent out.

UDP transport can only be used with the ZMQ_RADIO and ZMQ_DISH socket types.. Addressing. A ØMQ endpoint is a string consisting of a transport: // followed by an address.The transport specifies the underlying protocol to use. The address specifies the transport-specific address to connect to.. For the UDP transport, the transport is udp.The meaning of the address part is defined ESP32 WIFI Autoconnect and UDP Broadcast - Instructables
