FDO Revealed

So years after it's end - I figured I'd start a tutorial on FDO. Let's start with first principles. FDO is a binary display and control protocol.

The payload for specific tokens are refered to as "Atom Streams"

Here we have an example of a simple hello world message box

text source code
uni_start_stream <00x>
async_alert <info, "Hello World">
uni_end_stream
