Further functioning, but with bugs. Top line is working, but clear

there is messed up interplay between between how IOP updates its menu
and sends it to the Raduino, and how the Raduino updates its display.
Needs to be worked on.

Issues:
- After deselecting the I/O menu (i.e. should go back to normal Raduino
top line), it never does.  But the I/O menu is frozen.  So clearly the
top line never gets updated again by the Raduino.  Need to understand
the logic it uses to actually refresh the display.
- Random garbage (black boxes) on the top line--intermittently.
