Unsure, but after recent suggestions, it may be working.  Already had

I don't have a maintenance window but sounded like recent suggestions 
were easier.  Some official Slackware team members run SlackBuilds.org 
but its software isn't official... I call some quasi-official, and some 
gets added/redone for Slackware later.

I thought there was a lot more to it than that, but after I ran that 
stuff, the driver outputs.  However, /etc/rc.d/rc.ups initialization 
script might not do anything yet (only the command you gave, also when 
forked, or it will continue using the tty.)

Here's output I got within the last few minutes, just wondering how to 
complete configuration now (if this is working)...
