Problem Description: parallel port on 3/80 times out if busy line is asserted
                     for more than 33 seconds

      This shouldn't really be a bug. However, this
      patch provides work around for it. It would certainly
      be nice if we can make PTICKS user configurable.


INSTALL:
Example is for a sun3x running 4.1
 make sure and use your correct architecture and SunOS release.

As root:

save the origional version as a precaution.

# mv /sys/sun3x/OBJ/pp.o /sys/sun3x/OBJ/pp.o.save

copy the new versions. checking your architecture type and OS rev.

this tells you your architecture type
# arch -k

this tells you your SunOS Release
# dmesg |more

Now using your architecture and SunOS release information;
(example is for a sun3x running SunOS 4.1)

# cp sun3x/4.1/pp.o /sys/sun3x/OBJ/pp.o

rerun /etc/config <kernel-name>
