Move Cursor Down

Format:

1B 12

Description:

Moves the cursor down one line. When the cursor is on the 1-3, the

 

cursor is moved to the same column on the next row. When the cursor

 

is on the row 4, the cursor is moved to the same column on 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.
