I'm far from an expert (why I didn't respond at 1st), but I recently
got mine working so will offer what I can.

Just ensure that it is for the "new" version of the remote.  There
were 3 different versions that were incompatible (or so I've
heard--I've only got the new one).

Which screen does it do this on?  It is documented that in some
screens the numbers act like the cursor keys on a PC numeric keypad,
so indeed 8 would be up, 2 down, 4 left, 6 right.

If this is somewhere that numbers would make sense though ignore that comment.

Aha!!!  This sounds like what I had:

-  Boot up or restard lircd.
-  First irw returns immediately with no error
-  (lircd dies)
-  Subsequent irw invocations error out "connection refused."

If that is what you see, check your logs (/var/log/messages on FC3, I
presume on Debian as well) for an error about can't open /dev/lirc.
If that's the case, and /dev has a /dev/lirc0, modify your lircd
startup script to change

lircd

to

lircd -d lirc0

(from memory here.  Hope that's right.  Not at the box right now.  If
it doesn't like that argument, search the archives--that's where I
found it or post back and I'll check tonight).

Then kill and restart lircd.  Hopefully that fixes it.
