I find it hard to believe that broadcast doesn't work, too.  (-:

You've checked the basics, haven't you ?  You've checked that you've
configured a broadcast address for that interface in TCP/IP configuration, for 
example, yes ?

Try pausing the application after the call to bind() but before the call to
sendto() and using `netstat -s' to look at the socket address.  Try sending an 
ICMP datagram to the same broadcast IP address using `ping'.
