If you can tell me specifically where in the net.c source this line
should be added, I can try it right away.

Thanks-

The code is broken (if I am looking at the right version). All the
fields
of sockaddr_in are required to be initialized to 0. Try adding a:

        (void)memset(&sin, 0, sizeof(sin));

at the beginning of the function.
