Is it possible to do it in c?

@Hampusm To get cursor position, use ah = 03 | int 10h. This returns:

DL: Horizontal position
DH: Vertical position
CH: Start of scan line
CL: End of scan line

Hope this helps.

Ah sorry, I readed "how to GET cursor position" 😅 Use ah = 02 | int 10h to set cursor position. You need to include these parameters:

BH: Page (set it to 0)
DH: Vertical position
DL: Horizontal position 😅
