 This probably has to do with the fact that UDP is a connectionless protocol, 
ie no answer is expected to acknowledge a sent packet. Thus the scanner can 
not distinguish between an accepted package and one that has been dropped. 
Only a rejected package sents an response back to the scanner.

Bye,
Leonard.
