Software cursor for VGA by Pavel Machek <pavel@atrey.karlin.mff.cuni.cz>

Linux now has some ability to manipulate cursor appearance. Normally, you
-can set the size of hardware cursor (and also work-around some ugly bugs in
-those miserable Trident cards -- see #define TRIDENT_GLITCH in drivers/char/
-vga.c). In case you enable "Software generated cursor" in the system
-configuration, you can play few new tricks: you can make your cursor look
-like a non-blinking red block, make it inverse background of the character
-it's over or to highlight that character and still choose whether the
-original hardware cursor should remain visible or not. And maybe other
-things I have never thought of.

The cursor appearance is controlled by a "<ESC>[?1;2;3c" escape sequence
where 1, 2 and 3 are parameters described below. If you omit any of them,
they will default to zeroes.
- Parameter #1 specifies cursor size (0=default, 1=invisible, 2=underline, ...,
+ Parameter 1 specifies cursor size (0=default, 1=invisible, 2=underline, ...,
8=full block) + 16 if you want the software cursor to be applied + 32 if you
-want to always change the background color + 64 if you dislike background same
-as foreground. (Highlights are ignored for the last two flags.)

+background the same as the foreground. Highlights are ignored for the last two
+flags.
The second parameter selects character attribute bits you want to change
-(by simple XOR'ing them with the value of this parameter). On standard VGA,
-the high 4 bits specify background and the low 4 the foreground. In both
-groups, low 3 bits set color (as in normal color codes used by the console)
-and the most significant one turns on highlight (or sometimes blinking -- it

+groups, low three bits set color (as in normal color codes used by the console)
+and the most significant one turns on highlight (or sometimes blinking--it
depends on the configuration of your VGA).
- And the third parameter consists of character attribute bits you want
-to set. Bit setting takes place before bit toggling, so you can simply
-clear a bit by including it in both the set mask and the toggle mask.

+Examples:
+=========
+To get normal blinking underline, use: echo -e '\033[?2c'
+To get blinking block, use: echo -e '\033[?6c'
+To get red non-blinking block, use: echo -e '\033[?17;0;64c'
