Hi all,

I am quite new with developing applications using sockets. In order to 
understand Udp protocol I tried to
adapt UdpLstn example on Kylix. Mainly it requires only to replace TWSocket by 
TIcsSocket in the code.

Nevertheless it seems not enough : with the listener started on the port 55000, 
I send a datagram on this port
but triggerdataavailable is never called.

I checked with netstat that the port 55000 is open in udp and that the 
parameters of the IcsSocket are set
before calling the listen function.

The Listener remains stack into the select function (glibc) of the thread open 
by listen. So there are data to
read but no signal is viewed into Libc.select !!!

Would you have any suggestion ?

Many thanks
