Telnet Protocol specifications

RFC 495              TELNET Protocol Specification            1 May 1973


   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.
