I haven't had a chance to look at this before now, but I just read that 
link over.   Before I go ahead with step 3 (the only part that I need, 
from what I can gather), I wanted to make sure I had a good 
understanding of it.  If I "ls -l /dev/lir*", I get /dev/lircd and 
nothing else.  So,  from what I read there, the first thinng going on is 
2 LIRC devices being setup.  Can I assume that I only need the first 
line since I only have/need 1?

Second, in modprobe.conf, I see that COM1 is being setup and installed, 
but I don't really understand what the major numbers mean.  Actually, I 
understand what major and minor devices are, but I'm not sure if 61 
should stay as 61, or does the device # need to be something else?

I was going to try and make those changes and see what happened, but 
wanted to get those gray areas cleared up before I did.

Thanks,
Harry
