Thanks for the reply. I was afraid there wasn't an easy fix.

They are not identical, but have some of the same layouts. I figure I'd use as a starting point.

I don't have the file. Can I copy it from/off of the bedroom remote? Or do files only go one way from computer to remote? Looks like installation was back in 2006 based on the specs - sys v1.1 5/23/2001, app v1.1 5/23/2001, ccf 01/17/2006.

I do have an old laptop with serial port, anything special as far as the cable (#pins or something)? I figure i can get one at frys or ebay.

Thanks again.
