I think I've found your problem:

void asm_cursorshape(char start, char end);
#pragma aux asm_cursorshape = \
    "mov ah, 10h " \
    "int 10h" \
    parm [ch] [cl] \
    modify [ah];

void cursoroff() // Doesn't seem to work? (DOS box in windows)
{
     asm_cursorshape(38,3); // Start and end scan lines, 32 = invisible
}

void cursoron() // Doesn't seem to work in a DOS box
{
     asm_cursorshape(6,7);
}


It doesn't work because you're calling the wrong function -- function 
AH=10h is the palette control; you want AH=01h.
