Sorry Andy, but you are the one off on a tangent.  Here's the original
message from Tom Breza <tom@PCService-NET.co.uk>:

See that "SHIFT-PgUp"?  We have always been talking about clearing the
console scroll-back buffer.  Just clearing the screen is easy, that's
why this thread has shown several ways to do that.  Clearing the
scroll-back buffer is trickier.  Either one uses a logout script to fill
it with blank space (my suggestion) or the script switches to an unused
vt and back (Ethan's suggestion).  Got an ANSI code to do that?
