Description:
Clear the screen.
Description:
NTSC_GetXY(…) returns the position (column, row) of the virtual cursor. Depending on the driver
you are using, the (x,y) values have different possible ranges. For the Default2 driver they are
[0..31, 0..23]. The function takes two pointers to the integer variables you want to receive the
values. Returns 1.
NTSC_ClearScreen() simply clears the NTSC terminal screen and fills the screen with
spaces. Returns 1.
