Telnet Status Option

RFC 859                                                         May 1983


   The following is an example of use of the option:

      Host1: IAC DO STATUS

      Host2: IAC WILL STATUS

         (Host2 is now free to send status information at any time.
         Solicitations from Host1 are NOT necessary. This should not
         produce any dangerous race conditions. At worst, two IS's will
         be sent.)

      Host1 (perhaps): IAC SB STATUS SEND IAC SE

      Host2 (the following stream is broken into multiple lines only for
      readability. No carriage returns are implied.):

         IAC SB STATUS IS

         WILL ECHO

         DO SUPPRESS-GO-AHEAD

         WILL STATUS

         DO STATUS

         IAC SE

      Explanation of Host2's perceptions: It is responsible for echoing
      back the data characters it receives over the TELNET connection;
      it will not send Go-Ahead signals; it will both issue and request
      Status information.
