I have found that sometime when the unit powers up this port is dead.
How do I get this port to startup if it doesn't start?
I also want to hook up my own device to this port but it only outputs a heart beat message. How do I get it to output all of the Mavlink messages like Telem1 does?
Using Pixhawk with 3.2.1 currently.

I did get the second part working. I was finally able to send a message requesting all data streams.
I had a hard time as I didn't realize that when you use a packed message function that the check sum bytes are placed at the front of the buffer and not the end where it needs to be. Reorder the message and it worked. Getting all the messages now.
I also saw where I can set the baud rate and port use. Didn't see anywhere for the documentation about Frsky D-Port option though. I would assume that it's for the IRIS+ radio with OpenTx.
