Well I spent several hours on this now. I do see the format is wrong, I
changed to:
loadusr -W wj200_vfd baud=19200
But I've got it on a scope and it's still 9600 baud. And if I change it to
"baud=hahahhaha", there's no error for it being a non-number either.
Could the wj200_vfd code have a bug in accepting arguments?
