- Re: Turbo Cursor Off/On
-
- IBM-PCs have an official way to deal with screen functions. (This has
- *nothing* to do with MS-DOS, by the way). These routines aren't
- perfect, but there is little excuse for not using them unless you want
- something that they can't do.
-
- Turbo Pascal & compatible systems have a built-in routine called
- "intr" that makes interfacing to these routines easy. Most C compilers
- have a similar routine.
-
- INT 10, function 15 (ah register) gets you the screen mode. 7 is
- monochrome adapter, anything less is colour adapter or compatible,
- more is EGA or other card. Function 8 is cursor addressing. Put -1 in
- dx and the cursor goes away.
-
- (I will admit that the above -1 is not documented, but it's still
- better than poking around in the BIOS ram!)
