The array index numbers are of course garbage (from incomplete 
copy&paste editing), but somehow it worked nevertheless.

Should have been
   dadr.sin_addr.s_bytes[1] := 127;
   dadr.sin_addr.s_bytes[2] := 0;
   dadr.sin_addr.s_bytes[3] := 0;
   dadr.sin_addr.s_bytes[4] := 1;

Loopback appears to catch the whole loopback network, not just that 
single address.
