        February, 1975, Survey of New-Protocol TELNET Servers

  It has been two and a half months since our last survey, and it has
  been depressing to note that "progress" toward an all-new-protocol
  network has been even slower than previously.  Changes since the last
  list (with host numbers in octal):

  SRI-ARC (2) and OFFICE-1 (53) have added logger sockets 27, but with
     Old-Protocol servers (are these forerunners of New-Protocol
     servers?);
  SDC-CC (110) has been removed from the list until it starts operating
     on the network
  LL-67 (12) now has a New-Protocol server on socket 1;
  CASE-10 (15) has departed from the network;
  BBN-TENEX is now host 361 (formerly 105);
  ANL (ARGONNE, 67) has come on the net with Old- and New-Protocol
     servers on sockets 1 and 27, respectively.

  The following is the latest version* of the summary and tabulation of
  server-host Telnet servers.
          total server hosts             36      100%
          no New-Prot server             17       47%
          unknown status (new host)       1        3%
          total New-Prot implem.         18       50%
              New-Prot on socket 27,
                  Old on socket 1 (2)    10       28%
              New-Prot on 1 and 27 (3)    6       16%
              New-Prot on 1 only (3)      2        6%
  Notes:

  * All data in this report were gathered via a surveying program run
    at various times, plus a few manual checks to fill out the data.
    What is reported here is the way the various servers work as seen
    by the new-Protocol User Telnet at BBNA, as of 20 Feb. 1975.

  (2) These are the sites whose operation is 100% correct according to
      all protocols and conventions, as I understand them.

  (3) We realize that some of the servers that appear here as New-
      Protocol servers on socket 1 are actually servers which attempt
      to communicate with both Old- and New-Protocol User TELNETs
      according to what control sequences are received.

  Note: * These servers return improper responses to some TELNET option
  requests.
