Are you trying to hide a text-mode cursor? If not... disregard, nothing to see here...
I couldn't get writing a value directly to 0x0040:0060 for the cursor scan lines to do anything. I'm sure someone more expert than myself has a better solution.. but if you can't use int 0x10 ah=0x01, I think that you could:
- save the current cursor position in your data section
- set the cursor position to FF, FF or something else 'off screen'
- restore the cursor position when you need to write in teletype mode
Of course once you start doing all of this, you may as well write your chars directly to video memory too
, and just leave the cursor off screen.
Just a suggestion. If I'm not understanding your question correctly, just pretend I'm talking to myself. I'm comfortable with that.
