- There is a reason unix doesn't send some escape sequence out and see
- what comes back. That is because different terminals use different escape
- sequences for the command to return the terminal type. Other terminals don't
- have such a command. Escape sequences for some terminals lock up other
- terminals. Its really frustrating to the user to lock up their Banna-10
- terminal while checking to see if it responds to the ANSI escape sequence.
-
- Lowest common denominator. at least for the U.S., says that about the
- only thing that is safe to send out before the computer knows what kind of
- terminal it is talking to is, is 7-bit ascii (typically only printable and
- control characters).
