"reserved" means one "SHOULD NOT" use that port, where the phrase in  
caps is defined in RFC-2119 (http://www.ietf.org/rfc/rfc2119.txt).  And:

   http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

...states: "0/tcp,udp: Reserved; do not use (but is a permissible  
source port value if the sending process does not expect messages in  
response)"
