ESC[s Saves the current cursor position. Successive Save Cursor
Position commands overwrite previous positions saved.
ESC[u Restores the cursor position saved with a Save Cursor Position
command. Each Restore Cursor Position command must be
paired with a preceding Save Cursor Position command. If a
Save Cursor Position command has not been previously issued,
the cursor position remains unchanged
ESC[#w Defines the character set to be used (character sets are defined
later in this chapter). The character set to be used is specified by
the # parameter.
ESC[x Returns the display to the character set defined during
configuration.
Display Overflow
The reader can receive more data than it can display at one time. The display
overflow is stored in the virtual display image buffer of the reader. This buffer
holds up to four rows of the most recently displayed.
The reader display is a window or viewport into the virtual display image. The
2-line by 40-character display shows the last two rows by default. The 1-line by
20-character display shows the last row by default.
You use the review and forward commands to move the display up or down in
the current virtual display image. When you scroll the display up, the cursor is
disabled. When you scroll the display back to the default position in the virtual
display image, the cursor is restored.
Any event that alters the display returns the display to the default position. For
example, entered data, accumulated data, or commands (such as Enter,
Backspace, Clear, or End Accumulate) automatically return the display to the
default position.
