CCN NETRJS server messages to remote user

NIC #20268
                                                                     P.2


7          Finally, a valid signon will be acknowledged by RJS with the
          message:

               RJS750I TERMINAL -termid- HAS SIGNED ONTO RJS

     4.   If the user terminates the session by entering a SIGNOFF com-
          mand, NETRJS will wait until all data transfer has completed
          before sending the message:

               NRJ205R NETRJS SESSION TERMINATED

          and closing the Telnet connection.

     1.   During data transfer, the user must be reasonably responsive.
          If not, CCN will close the data transfer connection and send
          the remote operator message:

               NRJ504I DATA TRANSFER TIMEOUT FOR THE -device-, -termid-


                    a)   if -device- is PRINTER or PUNCH, user site
                         stopped accepting bits (sending "allocates")
                         for over 5 minutes.

                    b)   if -device- is READER, user site left reader
                         connection open without sending any bits for 5
                         minutes.

     2.   During data transfer on the CR connection, CCN may detect an
          incorrect header or record, presumably due to user site
          software or Network transmission error.  The following mes-
          sages beginning with the word "BAD" will follow an NRJ512I
          message containing the faulty header in hex:

               NRJ505I BAD HEADER SEQUENCE FOR NETRJS READER

                    Sequence number in transaction header does not match
                    internal counter of records passed.

               NRJ506I BAD HEADER LENGTH FOR NETRJS READER

                    Length given in header exceeds 880 bytes.
