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---->|<------?------>|
+---------------+---------------+-----------------+---------------+
|    leader     |    marking    |    checksum     |    padding    |
+---------------+---------------+-----------------+---------------+

                                Figure 1

                      Zero Text Length EOF Message
