Notes

  SRI-10:   The Telnet-like protocol differs from Telnet in
            that lines are terminated by X'OD' rather than
            X'ODOA'.  John Melvin will have it fixed by
            the time you read this.

                                                           RFC 193


  LL-67:    Joel Winett telles me NCP, ICP, EBCDIC, Telnet and
            access to a virtual 360 are working.  Due to hard-
            ware difficulties we have not verified this.
  BBN-10:   Same difference as SRI with respect to Telnet.
            Under certain conditions, the ICP generates a
            zero byte size.  Ray Tomlinson tells me these
            idiosyncracies will be taken care of in about
            a week.  Three sites have commented that TENEX
            assigns the same local socket to multiple connec-
            tions, when acting as a server.  Ray says that
            this is the design -- not an error.  BBN TENEX
            is currently being used productively via the
            Net, for some non-Network related problems.
  UTAH:     Our tests with UTAH were pre-TENEX.  TENEX is
            currently being installed at UTAH.
  MIT-645:  Our understanding is that most software is
            working; we have not verified this.
