It's an ANSI escape sequence, or rather two of them. The first one
clears the screen, the second returns you to 0,0. (Isn't that implicit
in the 2J code? Maybe I'm misremembering.) But it depends on the
terminal responding to them, and not all terminals do. For instance,
most MUD clients parse only a very small subset of ANSI codes, eg
color codes only.
