                       TELNET TIMING MARK OPTION


This RFC specifies a standard for the ARPA community.  Hosts on the ARPA
Internet are expected to adopt and implement this standard.

1.  Command Name and Code

   TIMING-MARK          6

2.  Command Meanings

   IAC DO TIMING-MARK

      The sender of this command REQUESTS that the receiver of this
      command return a WILL TIMING-MARK in the data stream at the
      "appropriate place" as defined in section 4 below.

   IAC WILL TIMING-MARK

      The sender of this command ASSURES the receiver of this command
      that it is inserted in the data stream at the "appropriate place"
      to insure synchronization with a DO TIMING-MARK transmitted by the
      receiver of this command.

   IAC WON'T TIMING-MARK

      The sender of this command REFUSES to insure that this command is
      inserted in the data stream at the "appropriate place" to insure
      synchronization.

   IAC DON'T TIMING-MARK

      The sender of this command notifies the receiver of this command
      that a WILL TIMING-MARK (previously transmitted by the receiver of
      this command) has been IGNORED.

3.  Default

   WON'T TIMING-MARK, DON'T TIMING-MARK

      i.e., No explicit attempt is made to synchronize the activities at
      the two ends of the TELNET connection.

4.  Motivation for the Option
