SendTo is the standard way to send UDP packets, since there is no
'connection' as such.

Yes, just make it a pointer:
tot := SendSocket.SendTo (SocRemAddr, SizeOf (TSockAddrIn),
@xmitline [1], Length (xmitline));
To make life easy, you can just use the Magenta Systems IP Log Streaming
Component from:
http://www.magsys.co.uk/delphi/magics.asp
which sends and receives TCP and UDP, and includes a EXE demo for testing,
run two instances and send UDP back and forward.
