Control Keys for Possible Programming
There are some keys on the 7802 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 through
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.
The Control keys can be used without pressing the ENTER key by using the Control Keys Only Terminal
Setup parameter. See the chapter on RF System Setup for details.
