$V	lock mode (screen will not scroll)
$W	unlock (screen will scroll normally)
$X	clear keyboard buffer?
$Ylc	positions cursor to line ASC(l)-32, column ASC(c)-32. If line or col
	 greater than screen limits then uses maximum possible value.

$e	starts flash mode (CRT only)

$l	clears line at cursor position
$n	prints "ESCY" & lc code for current cursor position (CRT only)
$p	start reverse mode

$z	DO NOT USE! Most of the time it does WIDTH 40 & clears the stored
	 cursor position. However sometimes it can cause a two-character delay
	 between when a character is sent to the screen & when it is actually
	 displayed. (ie type 123 & the 1 will show up as you type 3...)
