Rio (the window system) doesn't send any of the typed
characters until your press enter. This means that,
for example, you can edit the line using the mouse
if you make an early mistake that takes a while to
notice.
If you really want to get characters as they are typed,
you need to put the console in raw mode, by writing
"rawon" to /dev/consctl and then keeping the file
descriptor for /dev/consctl open.
I believe that then Bgetrune will give you runes
as they come in. However, you will be in charge
of echoing them to standard output.
