FYI - I did just get the OpenCockpits 767 COM Module working using the IOCModule Software (as is).  The standby frequency doesn't operate in the sim, but when I transfer to active, it is properly shown - so perfectly useable.
Opencockpits gives you the script to customize the NAV/COM control, but I have higher priority items to get working first...

I am still interested in anyone's experience with OpenCockpits and CS 767, as I have a TON of my custom scripts from another company FSX to  port over.  I suspect I may have to write a replacement to Lekseecon for syncing as he has no plans to port over to P3D CS767 :(
