RFC 255 October 1971 where D = Dead (Destination Host either dead or inaccessible [due to network partitioning or local IMP failure] from the BBN Terminal IMP.) R = Refused (Destination Host returned a CLS to the initial RFC.) T = Timed out (Destination Host did not respond in any way to the initial RFC, although not dead.) H = 1/2 Open (Destination Host opened a connection but then either immediately closed it, or did not respond any further.) O = Opened (Destination Host opened a connection and was accessible to user.) * The UCLA IMB-360/91 currently has Remote Job Service (NETRJS), but has not implemented a full server Telnet System. The BBN Terminal IMP is not equipped to test NETRJS however, we are assuming that receipt of the UCLA explanatory message indicates that NETRJS is also functioning. # These sites advertise that they may not have their system available at these times.
