>Description:
	puc(4) is a Universal driver for serial & parallel ports.  It supports
	variaous chips & boards except the one I bought from market, SUnix's
	daul ports parallel card with SUN1888 chip.
	
>How-To-Repeat:
	Plug a parallel port card with SUN1888 to your FreeBSD box and try to
	drive it with puc driver module.  Nothing is happening.
	puc(4) can not even recoganize the card.
	
>Fix:

	apply following small patch on src/sys/dev/puc/, and rebuild the
	module in src/sys/modules/puc/.
