+Request for Comments: 495 BBN-NET
+NIC #15371 1 May 1973
+Categories: TELNET, Protocols
+References: RFCs 318, 435; NIC 7104
+
+
+ TELNET Protocol Specification
+
+Following much discussion of TELNET via the RFC series, an open meeting
+was held at UCLA on 5 March to formulate a new specification for the
+TELNET Protocol. Two attached documents (TELNET Protocol Specification,
+NIC #15372, and TELNET Option Specifications, NIC #15373) report the
+results of that meeting, which was attended by: Alex McKenzie, BBN-NET,
+co-chairman; Jon Postel, UCLA-NMC, co-chairman; Bob Braden, UCLA-CCN;
+Vint Cerf, Stanford University; Bernie Cosell, BBN-NET; Dave Crocker,
+UCLA-NMC; Steve Crocker, ARPA; John Davidson, Univ. of Hawaii; Gary
+Grossman, Univ. of Illinois; Bob Merryman, UCSD; Lou Nelson, UCLA-NMC;
+Mike Padlipsky, MIT-MULTICS: Milt Reese, FNW; Bob Thomas, BBN-TENEX;
+Steve Wolfe, UCLA-CCN.
+
+
+The two attached specifications referenced above have been reviewed by
+the meeting attendees, and should be viewed as the "official" TELNET
+Protocol (subject to the implementation schedule given below).
+Nevertheless, these documents are still subject to minor revisions and
+any pertinent comments should be addressed to me at the NIC as AAM, or
+by mail at:
+
+ Alex McKenzie
+ Bolt Beranek and Newman Inc.
+ 50 Moulton Street
+ Cambridge, Ma. 02138
+
+ There are two key dates for a phasing in of the new protocol: the
+ date when sites should feel free to send the "new" form of TELNET
+ commands and special codes without expecting to receive "error"
+ responses, and the date when sites may remove the code which
+ processes the "old" form of TELNET commands. Between these two
+ dates, sites may gradually implement and test the "interpreter" for
+ the new commands. It was the sense of the meeting that appropriate
+ lead times to these two dates were about 60 and 260 days.
+ Accordingly, these two dates are hereby established as 1 July 1973
+ and 1 January 1974.

+
+
+ I have also attached specifications for TELNET options which allow
+ negotiation of:
+
+ o binary transmission
+ o echoing
+ o reconnection
+ o suppression of "Go Ahead"
+ o approximate message size
+ o use of a "timing mark"
+ o discussion of status
+ o extension of option code set
+
+ These specifications have been prepared by Dave Walden (BBN-NET) with
+ the help of Bernie Cosell, Ray Tomlinson (BBN-TENEX) and Bob Thomas;
+ by Jerry Burchfiel (BBN-TENEX); and by David Crocker (ULCA-NMC). It
+ appears that these options cover most of the capabilities of the
+ current version of TELNET, with the exception of "Hide Your Input."
+ Dave Walden has also promised to specify the following options in the
+ near future:
+
+ o NVT printer line width negotiation
+ o NVT printer page size negotiation
+ o negotiation of the mapping between the line terminator
+ character available on a physical terminal (e.g., LF,
+ CR, NL) and the NVT characters to be transmitted
+ (e.g., CR NUL, LF, CR LF).
+
+ Dave has also announced his intent to seek collaboration with
+ Gary Grossman, Bob Braden, and perhaps others in defining an
+ EBCDIC option. The announcement of intent to specify these
+ options should, of course, be seen as useful information rather
+ than as the granting of an "exclusive right" to Dave, or any
+ other author.
+
+ I gratefully acknowledge the assistance of Bernie Cosell
+ in the preparation of the protocol specification.
