[comp.sys.ibm.pc.hardware] Hardware interrupt from mouse

coxs@itsgw.rpi.edu (Sean Cox) (10/26/90)

       Does anyone know what hardware interrupt is generated by a (Logitech)
  bus mouse when an "event" happens? I need to chain into this innterrupt 
  for a screen saver, since it seems to be a more useful interrupt to use
  than the mouse driver polling interrupt.
       Thanks in advance. 
                                                -Sean

The logitech bus card has an IRQ setting. Take the IRQ, add eight to it,
and voila, you have your hardware interrupt!

Hope this helps...
