I finally got a chance to mess with this some more, and no luck, no matter which way i do it, using DCSBIOS_IRQ_SERIAL or DCSBIOS_DEFAULT_SERIAL, It still doesn't work. I'm just going to get a few more UNOs and try again. Thanks for the help.

I'll give changing the serial definition a shot later today. I figured having one Arduino for all 3 radios would cut down on the number of USB devices I need to have plugged in, as I want to make other panels still too.

I cannot seem to get an Arduino mega to work with DCS-BIOS, is there a compatibility issue that anyone knows about? I can't get it to do anything, even the basic master caution light flash, but if i plug in an Arduino Uno, or Nano and load the same sketch, it works fine, so i'm assuming it's not the sketch itself as that's the most basic task. Does anyone have any insights on this? I was hoping to build a custom radio stack with my kids as a fun project, and the mega would be perfect as it has enough I/O to do all 3 radios in the A10, but I just can't get it to work. As far as i Know, the mega isn't dead, as I can load up sketches and it will work standalone with switches and LEDs, so the circuitry seems fine. Thanks
