	You can inhibit use of your terminal when you need to leave it
	unattended by typing:

				BLP

	BLP will ask you for a 1 character escape code.  This is the only
	character BLP will later accept to exit.  After you have typed the
	carriage return, BLP will clear your screen and print a message
	that your "terminal is not functioning".  From this point on, BLP
	will accept no input except that special escape character.  When
	it receives that special escape code, BLP will return control of
	your terminal to you, and exit.

	NOTE - Be cautious about what escape code you use.  Some very
	special control and escape sequences may not give you what you
	expect.  If you can not duplicate the first character entered
	when you want to exit BLP; you will be stuck!
