             November, 1974, Survey of New-Protocol TELNET Servers

       Two months have elapsed since our last survey, and the appearance of
       additional New-Protocol servers has progressed at the usual snail's
       pace.  The changes in this list are (with host numbers in octal):

       SRI-AI (102) now has a New-Protocol server;
       SDC-LAB (10) is back on the net and the list;
       SDC-CC (110) is coming on the net but status is as yet unknown;
       USC-ISI (126) and USC-ISIB (226) (formerly ISI-DEVTENEX) now have
       New-Protocol servers;
       SDAC-44 (32) has been removed -- no longer classed as a server host;
       HAWAII-500 (344) is coming on the net, status presently unknown;
       LONDON (52) has been added;
       BBN-TENEXD is now host 162 (formerly 205).

       What follows is an update of the summary and tabulation that appeared
       in RFC #702.*  Is there light at the end of the tunnel?

             total server hosts             37      100%
             no New-Prot server             19       51%
             unknown status (new host)       2        6%
             total New-Prot implem.         16       43%
                 New-Prot on socket 27,
                     Old on socket 1 (2)     9       24%
                 New-Prot on 1 and 27 (3)    6       16%
                 New-Prot on 1 only (3)      1        3%

             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 4 Dec. 1974.

       (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.
