Yeah. It's pretty simple. Somewhere in memory (I dont' have my manuals at
the moment) is a byte with a bit that controls whether the BLINK bit in the
attribute bytes is actually blinking or background high intensity. Once you
have set this bit, you can program all 16 colors foreground and background
simultaneously, although blinking has been disabled. Does this make sense?
Here's what the attribute byte breaks down to:
BL r g b I r g b
7 6 5 4 3 2 1 0
bit numbers ^^^^
BL is BLInking (or hi-intensity if blink is disabled)
r is red
g is green
b is blue
I is high intensity.
hope this helps.
