Your second gopen() is using the wrong driver (I think).  Its seems wrong 
to do this, but instead of using the hp-hil driver which is geared to 
talking with physical hardware (eg, /dev/hil1), use the display driver.  In
your case, "hp98550" should be used.  Any input resources attached to the
X window are then passed on to Starbase via the hp98550 driver whenever
the window has the input focus.  I suspect your 3rd gopen() needs the 
same change.
