+Depending on the protocol used for the current session, there may be
+a submenu of \q{special commands}. These are protocol-specific
+tokens, such as a \i{\q{break} signal}, that can be sent down a
+connection in addition to normal data. Their precise effect is usually
+up to the server. Currently only Telnet and SSH have special commands.
+
+The following special commands are available in Telnet:
+
+\b \I{Are You There, Telnet special command}Are You There

+\b \I{Break, Telnet special command}Break
+
+\b \I{Synch, Telnet special command}Synch

+pressed; see \k{config-telnetkey}.
