The ansi escape sequence is ESC[2J
That will clear the entire screen. This method works fairly reliably in
my experience with telnet clients of various types.
I have a reference I found one day (I cannot recall where) and keep it
online at http://stormpunk.com/colour/ansi.txt
After clearing the screen, one may wish to reset the character position
to home (0,0)
One can do this with the sequence: \033[2J\033[0;0H
\033 being escape.
Of course, if your client doesn't handle ansi, you could always just do:
print "\n" x 25
Other ways abound
