I could have discussed with you the fact, that you want an unreliable
protocol to reliably transfer data.

I could have discussed with you the fact, that you sent 32k(!) of HTML
formatted email to 600 subscribers of this mailing list, 19 MBytes in total.

But I do not. ;-)

Have a look at
http://www.ethernut.de/api/group__xg_udp_socket.html

Basically
 NutUdpSetSockOpt(sock, SO_RCVBUF, &udp_bufsiz, sizeof(udp_bufsiz));
should do the trick.
