CH59x printf does weird stuff on strings longer than 7 chars

Apparently I did not test this well enough, this needs fixing. Just putcharring with a delay works, so probably printf does it too quick?

Perhaps it needs some sort of "ready for transmit" handshake/checking like the non-CH59x case?

that is very possible, I just copied this from the EVT. Very possible that I missed something like this, thanks!

this was fixed in #570 (i thought that gh would close this automatically after merge)
