4-9-1 TCP/IP Discoverer
The COTEK TCP/IP Discoverer PC project (formerly known as the D11 Ethernet Device
Discoverer) will aid in embedded product device discovery (with the Announce protocol) and
will demonstrate how to write PC applications to communicate to D11 devices.
When the "Discover Devices" button is clicked, this application will transmit a broadcast UDP
packet containing the message. If any embedded devices with the Announce protocol
enabled are connected to the network, they will respond with a UDP packet containing their
host name (NBNS) and MAC address.
