the serial cable connected.
After you power the Base up, plug in the serial cable. You will
not
see the
“

” message but it should not matter when testing for the
garbage data.
If a terminal is signed-on to the system, and the base station is re-initialized,

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.
The Control keys can be used
without
pressing the ENTER key by using the
