salve scorrpeio,

Something looks a bit dubious.
Are you positive on this line: m_RemoteAdd.sin_port = htonl( INADDR_BROADCAST ); ?
INADDR_BROADCAST is usually a placeholder for the bcast addr 255.255.255.255.

You should pass a port number. INADDR_BROADCAST is equivalent to 0xffffffff.
sin_port being an unsigned short gives you portnumber 65535. Is this your intended usage ?

Also check the send/receive buffer sizes.
