They do look pretty good, given a quick skim, but I find that the best test is to actually use the modules and then see if I can easily find what I need to know. And … I’ve not tried to use them yet.
I don’t go out looking for documentation just to review it. I just stumble upon it as needed.
I am nostalgic for the days when you would buy, say, a 2400 Bd modem, and it came with a manual the size of the O.E.D.
