I am using xe7.1 and I need to make a cross platform application that uses 
TIdUDPServer 

I will exchange UDP packets with other devices in the same network

However i need to:

1) know if there is a network available (no need of internet, just a local 
network)
2) calculate the broadcast ip, since using the 255.255.255.255 is blocked 
in many home routers.

I prefer using Indy in a way that can be trully cross platform. 

Many thanks for any help...

Eduardo

PLEASE IGNORE THIS POST.... SOMEHOW MY NNTP CLIENT DUPLICATED IT
