UDP VC++ Echo problem in server program

Hi:
I have a UDP server program where all I want to do is broadcast out a
universal message on 192.168.0.255 (if 255 is a universal broadcast ->
255.255.255.0 will not work b\c my router will stop it).

I keep getting back my echo (12345678) instead of the client response
(23456789).

Please help. code follows:(BUFFER is defined as 8)
