Just use the dos interrupt 0x33 to access the mouse, for example:

        union REGS      rg;

        rg.x.ax = 3;            /* Get button status and mouse position */
        int86(0x33, &rg, &rg);

         x = rg.x.dx >> 3;
         y = rg.x.cx >> 3;
         buttons = rg.x.bx;

The buttons are the low order bits.

There are similar calls to set the mouse esolution, speed and position.
