[ILUG] More Upgrade woes

[Burke, Gary : GIG IS&T]

Is /dev/lp0 there?  Does it exist.   ls /dev/lp0 and see if you get
anything.  If not, then...

cd /dev
./MAKEDEV lp0

and then try again.  If it does exist, do a 'file /dev/lp0' and it will tell
you the major and minor numbers, and what type of device it is (character,
block, etc).


Probably not this, but you'd never know.
