duplicate commands with multiple transceivers

[bcboy@xxxxxxxxxxxxxxxxxx]

I've read the bit about multiple transceivers here:
http://www.mbx-usa.com/multiples.htm. I'm using two RR501s, one X10
branded, one IBM branded, on the same house code, and I see duplicate
dim commands on unit 5. I haven't tested other codes, but this seems to
contradict the information on that page.
