           Specification Changes for
           OLS, RJE/RJOR, and SMFS

 The following documents are hereby revised:

 (1)  'Specifications for Network Use of the UCSB
      On-Line System [16 October 70, RFC 74, NIC 5417],

 (2)  'Network Specifications for Remote Job Entry and
      Remote Job Output Retrieval at UCSB' [22 March 71,
      RFC 105, NIC 5775], and

 (3)  'Network Specifications for UCSB's Simple-
      Minded File System' [26 April 71, RFC 122,
      NIC 5834].

 Revisions are as follows:

 (1)  As far as can be determined, no Network site has
      written code to interface to the UCSB software
      documented in RFC 74 last October.  Accordingly,
      UCSB has terminated support for that software,
      and hence RFC 74 is obsolete.

 (2)  In accordance with subsequent Host-Host protocol
      changes, the notion of 'message type' has been
      dropped from the specifications for RJE and RJOR,
      RFC 105.  RJE/RJOR no longer send, nor expect to
      receive 8 bits of zeros as the first byte trans-
      mitted over a connection.

 (3)  In accordance with Document 2, RJE and RJOR now
      employ a standard ICP to create a full duplex
      connection to the user.  Accordingly, RJE and
      RJOR listen on sockets x'201' and x'301',
      respectively (rather than on x'200' and x'300'
      as before).  As documented in RFC 105, RJE
      required only a simplex connection to the user.
      A full duplex connection is now supported, but
      no data is transmitted to the user over the

NIC 7547

      added simplex connection.  RJOR now also supports
      a full duplex connection.  However, if RJOR is
      required to call the user back when a requested
      job's output is ready, it still does so employing
      a simplex connection to the user's receive socket.

 (4)  RJE/RJOR and SMFS specify a byte size of
      eight for their connection to the user's
      receive socket.  The user may choose the
      byte size for the other simplex connection
      to suit himself;  any valid byte size is
      acceptable to UCSB.
