Optional Settings for Predefined Messages
Each predefined message can be configured with optional controls which the OIT will
perform either before or after a message is displayed on the OIT screen. These controls
are provided to minimize the amount of commands that must be sent from the host in
order to format the OIT display screen.
Controls used before displaying the message: Each predefined message can be tagged
with one of the following controls. These controls are performed on the OIT before the
message is displayed:
• No Action - selecting this option means that nothing is done to the OIT display before the pre-
defined message is displayed.
• Clear Screen - the OIT clears the entire screen and homes the cursor.
• Clear Line - the OIT clears the entire line that the cursor is located on and moves the cursor to
the beginning of the line.
• Clear to End of Line - the OIT clears the entire line starting at the current position of the cursor.
Controls used after displaying the message: Each predefined message can be tagged
with one of the following controls. These controls are performed on the OIT display after
the message is displayed:
• No Action - selecting this option means nothing is done to the OIT display after the predefined
message is displayed.
• CR (Carriage Return) - the OIT moves the cursor to the beginning of the line that the cursor is
on after the message is displayed.
• LF (Line Feed) - the OIT moves the cursor to the beginning of the next line after the message is
displayed.
• VT (Vertical Tab) - the OIT performs a ‘reverse line feed’ by moving the cursor to the begin-
ning of previous line after the message is displayed.
• Cursor to Start of Msg - the OIT moves the cursor to the first character of the message that was
just displayed.
