Browsed over those threads. Most are about the com 1 port and the serial to usb cable not working . Mine works fine. I can connect and download a ccf from the computer to the pronto just not the other way around all of the sudden so that is why I want the file for the DTV hr21 and then just add it to my ccf and dl to my pronto. So that is where we are at. How to copy those codes in pcf format and save them in a ccf to use on my pronto.
