Abstract
--------

	This PTF contains updates to the UnixWare keyboard driver.  
	These updates prevent the shift key from being stuck on.


Symptom
--------

	A fast typist might occasionally see the shift key be stuck
	in the ON mode.  That is, all key presses would behave as
	if the shift key were being simultaneously pressed.  The
	shift key sticks on until the shift key is pressed again.


SOLUTION SPECIFICS
------------------

General Description.
-------------------

	The updated driver saves the scan codes from the keyboard
	so that they are not lost when the keyboard is reset.  Thus,
	the release code from the shift key will be seen by the
	driver and the shift key will behave properly.


New Features.
------------

	None

Software Notes and Recommendations.
----------------------------------
	
	This PTF can be installed on UnixWare 2.0, 2.0.1 and 2.0.2
	systems.
