              Who Talks TCP? - Survey of 1 February 83

The list of hosts was taken from the NIC hostname table of 28-Jan-83.
The tests were run on 1-Feb-83 from 10 am to ~1:00 pm PST, and on
    2-Feb-83 from 8 am to ~11:15 am PST from ISI-VAXA.ARPA
Dead, refused, and unreachable hosts were retried 3-Feb-83 from ~8 am
     to ~1:20 pm PST.

Claims are taken from the NIC host table:
        T = tcp (no particular services mentioned)
        t = tcp/telnet
        f = tcp/ftp
        s = tcp/smtp

Results for each service:
        blank (not accepted)
        refused
        unreachable
        dead
        accepted
        accepted+ (FTP allowed user anonymous, password guest)
