The front panel keypad controls the local operation of the modem. The keypad consists of 18
keys. Each key provides one or more logical functions.
[ENTER] This key is used to select a displayed function, or to execute a modem
configuration change.
[CLEAR] This key is used to back out of a selection, or to cancel a configuration change,
which has not been executed using [ENTER]. Pressing [CLEAR] generally
returns the display to the previous selection.
g and h These keys are used to move to the next selection, or to move the cursor for
certain functions.
i and j These keys are used primarily to change configuration data (numbers), but are
also used at times to move from one section to another.
Numbers These buttons are used to enter a numerical value manually.
+/- The +/- buttons allows the user to change signs.
IMPORTANT
The keypad has an auto-repeat feature. If a key is held down for more
than 3 second, the key action will repeat, automatically, at the rate of 7
keystrokes per second.
