   kind.  Discussion and suggestions for improvement are requested.

Abstract

   This document specifies a mechanism for passing character set and
   translation information between a TELNET client and server.  Use of
   this mechanism enables an application used by a TELNET user to send
   and receive data in the correct character set.

   Either side can (subject to option negotiation) at any time request
   that a (new) character set be used.

1.   Command Names and Codes

   CHARSET.......................42

      REQUEST ....................01
      ACCEPTED ...................02
      REJECTED ...................03
      TTABLE-IS ..................04
      TTABLE-REJECTED ............05
      TTABLE-ACK .................06
      TTABLE-NAK .................07

   As a convenience, standard TELNET text and codes for commands used in
   this document are reproduced here (excerpted from [1]):

      All TELNET commands consist of at least a two byte sequence:  the
      "Interpret as Command" (IAC) escape character followed by the code
      for the command.  The commands dealing with option negotiation are
      three byte sequences, the third byte being the code for the option
      referenced. ... [O]nly the IAC need be doubled to be sent as data,
      and the other 255 codes may be passed transparently.  The
      following are [some of] the defined TELNET commands.  Note that
      these codes and code sequences have the indicated meaning only
      when immediately preceded by an IAC.
