Reader warning messages
All error or warning messages to the operator. These
messages can interrupt the current display at any time and are generally
accompanied by a beep. If transparent display is selected, the error messages
are not displayed.
Display Settings and Formatting
The reader has two display settings: buffered and transparent.
Buffered Display
In buffered display mode, the reader adds and executes a CR LF sequence to
all transmitted, received, or scanned data or messages. The CR LF formats the
reader display to show each record, message, or prompt on a new line.
After displaying a host message, the reader adds a CR LF sequence is to any
accumulated data. The CR LF is then executed and any buffered accumulated
data is displayed again on the next display operation.
Transparent Display
In transparent display mode the display does not format data or host messages
with CR LF sequences. You use control codes or control sequences in host
messages or IRL prompts to format data for the display.
Formatting the Display
You use control codes to position the cursor or format the reader display. The
reader recognizes these display control codes:
Description Code Action
Backspace
BS (08 Hex)
Moves the cursor one position to the left until the cursor reaches
the first column. Except when in the first row, the cursor moves
from the first column of the current row to the last column of
the previous row.
Home
CR (0D Hex)
Returns the cursor to the first column of the current row.
Next line
LF (0A Hex)
Moves the cursor down one row in the current column position.
If the cursor is already in the last row, a new line is added.
Erase Display
ESC[2J
Erases all of the display and returns the cursor to the home
position (row 1, column 1). Erases the entire virtual display
image (buffer with up to four rows of the most recently
displayed data).
