It doesn't provide them because why do you need to know? The attached
device should request the settings it needs and be done with it. Maybe
some devices can support a number of settings and you could want
negotiate the settings with the UART, though surely 8N1 is in that
list. It's rare to see something that's not 8N1 from what I've seen.
