Before you can use the keys on the front panel to enter ASCII characters, the
VX 680 terminal must be in a mode that accepts keyed data entry. There are two
terminal operating modes, each enabling you to press keys to enter data under
specific circumstances:
•
Normal mode: This is the terminal operating mode where an application
program is present in mDRAM and currently running.
•
Verix Terminal Manager (VTM) mode: This is a special, password-controlled
terminal operating mode for performing a variety configuration procedures that
cannot be performed when an application is running.
If you enter Verix Terminal Manager while a terminal application is running in
normal mode, Verix Terminal Manager preempts the application and takes control
of the display and keyboard. The only way to exit Verix Terminal Manager is to
restart the terminal. For this reason, once you enter the Verix Terminal Manager,
you cannot return to the application in the same session.
If you turn on a VX 680 terminal with an application stored in memory and *GO
variable set to the application name, the application executes and the terminal
automatically enters normal mode. The application then controls how terminal
keys process transactions and when you can use specific keys to type characters
or respond to prompts.
The keypad is a 13-key arrangement, consisting of a 12-key Telco-style keypad
(Figure 2).
The VTM functions described in the
to enter numbers, letters, or symbols using the keypad.
Using the keypad, you can enter up to 50 ASCII characters, including the letters
A–Z, the numerals 0–9, and the following 20 special characters: (*), (,), ('), ("), (-),
(.), (#), (%), (:), (!), (+), (@), (=), (&), (space), (;), ($), (_), (\), and (/).
Alphabetic characters are entered by pressing its corresponding number in the
keypad multiple times within a given time.
