Control Keys for Possible Programming
There are some keys on the RF Terminal keypad that when pressed, can transmit
special ASCII characters back to the host program. This feature might be used
by a programmer to allow the operator to review transactions. You can use
these keys for special program functions, such as scrolling thru data,
backing up steps, jumping, finishing a process, etc The keys are as follows:
Key Code transmitted to Host
UP ARROW key FS (ASCII 28)
DOWN ARROW key GS (ASCII 29)
LEFT ARROW key RS (ASCII 30)
RIGHT ARROW key US (ASCII 31)
BEGIN key ETB (ASCII 23)
END key CAN (ASCII 24)
SEARCH key VT (ASCII 11)
The STATUS key is reserved to only display the Time and Date.
For these codes to be transmitted, there are a few rules to follow:
• They cannot be part of a multi-character data entry. In other words, they
cannot be used in combination with other data. If another key has been
pressed, these special keys are ignored. If you are using the SHIFTED
character on one of the special keys, it is accepted as the shifted character.
• For these keys to be transmitted, they must be pressed individually and
exclusively and MUST be followed by the ENTER key.
The ARROW keys can be used without pressing the ENTER key by using the
Arrow Keys Only Terminal Setup parameter. See Chapter 2; RF System Setup
for details.
