[REPOST because of missing patches]
I would like to submit the following patches to linux-2.5.7-dj1 so that:
* The "software" cursor (activate using "echo -e '\033[?17c') works like in
"xterm":
it merely inverses the current (color) attributes of the current underlying
character instead of having a fixed color
This changes affects hardware text mode and graphics framebuffers
* Blank char attributes are set equal to current char attributes
(so that the new software cursor displays properly)
* Text blinking attribute is disabled while in hardware EGA/VGA color textmode
so that all 16 background colors are available
--> echo -e '\033[5m' activates "bright background"
Examples:
$ echo -e '\033[17c'
$ echo -e '\033[32;44;1m'
The text is bright green over blue
The cursor is blue over bright green
$ echo -e '\033[m\033[30;43;5m'
The text is black over yellow
The cursor is yellow over black
I would suggest that similar changes are made for the framebuffer's "hardware"
cursor so that it has "xterm -bc"-like behavior.
