But.... Why do you want to do this. You realize that by bypassing the MOUSE.COM program, you render your program incompatible with any mouse that isn't MS compatible. For instance, my Genius mouse, or my roommate's Mouse Systems mouse wouldn't work that way, since they are only compatible with the mouse interrupt, not with the serial port signals. Also, a bus mouse wouldn't work with your scheme.
