+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.
