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/video/ -vgacon.c). You can now play a 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. There may be 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, ..., -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 having the -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 simply XORing them with the value of this parameter). On standard VGA, -the high four bits specify background and the low four the foreground. In both -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). - - 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' |
