Thanks everyone for looking into this for me. A couple of points of clarification. The T2 that I referred to is the RTI remote that I use. Many years ago, when I first got the T2, I used to be able to access Pronto ccf and hex codes using ProntoEdit (not the 4.0 version). It's been awhile since I've done this, but I can't seem to be able to get to the Krell HTS 7.1 Pronto hex codes to copy to my T2. At least not the way that I remembered, which is to use ProntoEdit (in this case 4.0) software to display the Device. Then on the right hand side, there would be the buttons that I would see. I would double left click on the button, which (I thought) would display the hex codes for that command. I would then copy the hex codes from Pronto and paste on to my RTI T2 remote hex window for that command.
So, I'm not sure if why this doesn't work anymore. Maybe the ccf file that I received is bad. I sent John a copy to see if he had any luck.
