+\H{using-supdup} Connecting using the SUPDUP protocol
+
+PuTTY can use the SUPDUP protocol to connect to a server. SUPDUP is a
+login protocol used mainly by PDP-10 and Lisp machines during the
+period 1975-1990.  Like Telnet and Rlogin, it is unsecured, so modern
+systems almost never support it.
+
+To make a connection of this type, select \q{SUPDUP} from the

+set, more processing, scrolling), you can use the \q{SUPDUP}
+configuration panel (see \k{config-supdup}).
