Moving text mode cursor not working

Question

Answer 1

You select wrong VGA registers. You have to use 0x0F for low and 0x0E for high (you have 0x0A for both).

Edit: In case your cursor is disabled, this is how to enable it:

void enable_cursor() {
    outb(0x3D4, 0x0A);
    char curstart = inb(0x3D5) & 0x1F; // get cursor scanline start

    outb(0x3D4, 0x0A);
    outb(0x3D5, curstart | 0x20); // set enable bit
}

Edit2: Your cursor location variable is not wide enough to store the cursor location. unsigned char cursor_loc should be unsigned short cursor_loc.
