// UDPDaemon - an example console application that utilizes the WSJT-X
|
|
// messaging facility
|
|
//
|
|
// This application is only provided as a simple console application
|
|
// example to demonstrate the WSJT-X messaging facility. It allows
|
|
// the user to set the server details either as a unicast UDP server
|
|
// or, if a multicast group address is provided, as a multicast
|
|
// server. The benefit of the multicast server is that multiple
|
|
// servers can be active at once each receiving all WSJT-X broadcast
|
|
// messages and each able to respond to individual WSJT_X clients. To
|
|
// utilize the multicast group features each WSJT-X client must set
|
|
// the same multicast group address as the UDP server address for
|
|
// example 239.255.0.0 for a site local multicast group.
