 9  // for a moment at the end of the reading).  Additionally, the "\x4\x5" at
10  // the end of some messages tells it to scroll to the left and right ends
11  // of "GOOD BYE" on the board.  Other points one can focus on:
12  // \x1 "YES"
13  // \x2 "NO"
14  // \x3 "GOOD BYE" center
15  // \x4 "GOOD BYE" left
16  // \x5 "GOOD BYE" right
