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.
