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.Dodds                                                           [Page 1]
