Disable Character Blink

1B 0E
This command counteracts the Enable Character Blink. The firmware
will implement all new character codes with an on and holding
character presentation. On power up, the character blink modifier is
defaulted to disabled.

Move Cursor Left

1B 0F
Moves the cursor one position to the left. When the cursor is at the left
end of the rows 2‐4, it moves to the right end of the row above it. When
the cursor is at the left end of the row 1, it moves to the right end of the
row 4. The cursor location always indicates the position of the next
character to be displayed, whether the cursor is enabled and blinking
or not. After each character is displayed, the firmware performs a
logical Move Cursor Right command.

Move Cursor Right

1B 10
Moves the cursor one position to the right. When the cursor is at the
right end of the row 1‐3, it moves to the left end of the next row. When
the cursor is at the right end of the row 4, it moves to the left end of the
row 1. The cursor location always indicates the position of the next
character to be displayed, whether the cursor is enabled and blinking
or not. After each character is displayed, the firmware performs a
logical Move Cursor Right command. When the cursor is at the right
end of the row 4, it moves to the left end of the row 1 and operates in
an Overwrite Mode. (i.e., The next character sent to the display will
overwrite the character in the left end of the row 1.)
