"\x1b[2J" or ESC [2J should clear the screen and

"\x1b[1;1H" or ESC [1;1H should move the cursor to the origin (I got that 
wrong in the previous post)

There may be other problems -- I stopped reading

http://en.wikipedia.org/wiki/ANSI_escape_code

as soon as I got the desired effect (scrolling) in konsole.
