ing a letter key while holding down the <Ctrl> key. Alter-
nate commands may be freely mixed with the keyboard
commands at the user’s discretion. The alternate command
keys are listed in the following table.
4.1.6 Field Types
Each screen is made up of fields. The two basic types are
‘user selectable’ and ‘display only’. If the highlighted cursor
can be moved to a field, it is a ‘user selectable’ field. All
other fields are ‘display only’. User selectable fields allow
for changes to be made or commands to be executed.
Fields without brackets or parenthesis are ‘display only’
fields. They cannot be changed on the screen. Most ‘user
selectable’ fields are enclosed in brackets or parenthesis and
are described in the following paragraphs. Any exceptions
are noted in the appropriate section of this manual.
Fields enclosed in brackets [ ] offer the user a list of selec-
tions from which to choose. The selections may be toggled
by pressing the spacebar. Each time the spacebar is pressed,
a new item appears. When the appropriate choice is dis-
played, press <return> to select it.
Fields enclosed in parenthesis ( ) are manipulated by one
of the following two methods:
1) Pressing <return> on such fields as ( Reset ) and
( Start Test ) simply execute the function.
2) The most common type of field in parenthesis accepts
typed input in the form of letters and/or numbers. Typing
characters when the field is highlighted causes the current
entry to be replaced with the new characters. To edit an
existing entry rather than replace it, press the <right arrow>
key to move the cursor to the point that needs editing. Char-
acters may then be inserted or deleted. Typed data is always
inserted rather than typed over. If the field is full, though, at
least one character must be deleted to add another.
Many fields of this type may also be toggled by pressing the
<spacebar>. Other fields are range checked, where the user
is not allowed to exit with an illegal value set.
NOTE: Any changes to fields on a screen that have not
been activated by pressing <return> will be discarded.
NOTE: Any screen may be redisplayed (or refreshed)
by pressing <Ctrl - U>.
4.2 Main Menu Screen
The ‘Main Menu’ screen (refer to Screen 4-2) lists the func-
tional menus accessible by the user. To activate any menu,
highlight the desired selection and press <return>. This
menu and any subsequent menu may be exited by pressing
<esc>. If the ‘Main Menu’ is exited, the Terminal Interface
program terminates. This is a valid way to end a user ses-
sion. If any other menu is exited, the user is returned to the
previous screen.
NOTE: If the keyboard is inactive for a 10-minute
period, the Terminal Interface logs off automatically. To
manually log off, press <esc> from the ‘Main Menu’.
