RFC 13

20 August 1969
Referring to NWG/RFC: 11, it appears that file transmissions over
auxiliary connections will require some mechanism to specify "END-OF-
FILE." It is proposed that a length 0 (zero) message be used for this
purpose. Figure 1 shows the format:
|<---32 bits--->|<---32 bits--->|<----16 bits---->|<------?------>|
