Summary: ^^ (octal 36)
We use octal 36 (^ on many terminals). It is also used by
the arpanet telnet software I'm familiar with.
Since it is only one character long, we don't have to worry about
whether programs use it or not. The network software, both terminal
servers and arpa telnet, passes it through if it is followed by another
^^. In other words, ^^ is a "command-prefix " character. If it is
followed by one of the command characters, say x for escape to command
level, then that action is performed. If another character
follows, then that character is sent. Since ^^ isn't a command
character....
Of course the command-prefix character can be changed by the user.
There is also a setting allows you to use break (which isn't ascii)
to get to terminal server's command level.
