Set the String Display Mode, and Write String to Display

Upper Line Message Scroll Continuously
Move Cursor Left
To set the String Display Mode, write to the upper or lower line.
d1 d2 d3 ..... dn {1≦n≦20}
A = upper line
B = lower line
The String Display Mode is cancelled and returns to the last mode after
receiving the CLR or CAN command.
The message (previously defined) scrolls continuously in the
horizontal direction until a new command is received.
This command moves the cursor to the left. It operates differently
when the cursor is at the beginning of the line, depending on which
display mode is used.
Overwrite Mode: When the cursor reaches the beginning of the lower
line, it then moves to the end of the upper line and overwrites the
previous character. When it reaches the left end of the upper line, it
then moves to the end of the lower line.
Vertical Scroll Mode: When the cursor reaches the beginning of the lower
line, the lower line then scrolls up and replaces the upper line. The
lower line is cleared and the cursor moves to the end of the lower line.
Horizontal Scroll Mode: The cursor remains stationary.
