Sorry if the above sounds like an insult. I certainly hope I did not
offend you.
Regarding my problem: As long as I keep a TSnmpSend instance open and
call TSnmpSend.RecvTrap in a loop I do not loose any UDP packages,
correct? At least if my background thread has a high enough priority and
my machine is capable to handle the traffic.
Thanks again for providing Synapse!
