UDP question

Andre,

I had a similar problem when I tried to broadcast over UDP. I wanted  
a client to broadcast and a server to reply. AFAIK Revolution cannot  
do that. I solved it by having the server open a new connection to  
the client. Since you're sure that the client will reply, this can be  
a normal connection, which allows you to keep the connection open as  
long as necessary.

Best,

Mark
