4-4. Direct Mode 2
Besides the standard communication mode, we could accept direct command to display
text easily. The cursor concept is implemented. When the host sends some ASCII text to
the panel, it will display the text in the current cursor position. The following commands
are supported.
4-4-1. Select Overwrite Mode
0x1B
0x11
In overwriting mode, entering a character code moves to the left end of the lower line when
the cursor is at the right end of the upper line, and to the left end of the upper line when the
cursor is at right end of the lower line. When the power is turned on, this mode is selected
by default.
4-4-2. Select Vertical Scroll Mode
0x1B
0x12
In vertical scroll mode, entering a character code moves the cursor to the left end of the
lower line when the cursor is at the right end of the upper line, scrolls the characters
displayed on the lower line, and clears the lower line when the cursor is at the right end of
the lower line. At this time the cursor is moved to the left end of the lower line.
4-4-3. Select Horizontal Mode
0x1B
0x13
In horizontal scroll mode, entering a character code scrolls all displayed characters one
character to the left, then displays the new character at the right end.
4-4-4. Move the cursor one character position to the left
0x1B
0x5B
0x44
or
0x08
When the cursor is at the left end of a line, the operation of this command depends on the
display mode.
- Overwrite mode: When the cursor is at the left end of the lower line, it is moved to the
right end of upper line. When it is at the left end of the upper line, it is moved to the
right end of the lower line.
- Vertical scroll mode: When the cursor is at the left end of the lower line, it is moved to
the right end of the upper line. When it is at the left end of the upper line, the display on
the upper line is scrolled to the lower line and the upper line is cleared. At this time the
cursor is moved to the right end of the upper line.
- Horizontal scroll mode: All characters on the current line are scrolled one character to
the right. The cursor is not moved, but the character area at the left end is cleared.
4-4-5. Move the cursor one character position to the right
