\C{using} Using PuTTY
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. Currently only Telnet and SSH
-have special commands.

+up to the server. Currently only Telnet and SSH have special commands.
-\# FIXME: possibly the full list of special commands should be
-\# given here, if only so that it can be sensibly indexed and
-\# someone looking up (e.g.) AYT can find out how to send one?
+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

+\b \I{Erase Character, Telnet special command}Erase Character

+PuTTY can also be configured to send this when the Backspace key is
+pressed; see \k{config-telnetkey}.

+\b \I{Erase Line, Telnet special command}Erase Line

+\b \I{Go Ahead, Telnet special command}Go Ahead

+In an SSH connection, the following special commands are available:

SSH server machine can connect to the forwarded port.) Note that
this feature is only available in the SSH 2 protocol, and not all
-SSH 2 servers support it (OpenSSH 3.0 does not, for example).
+SSH 2 servers honour it (in OpenSSH, for example, it's usually
+disabled by default).
You can also specify an \i{IP address} to listen on. Typically a
Windows machine can be asked to listen on any single IP address in

theory but servers will not necessarily cooperate.
