4-4 T ERMINAL O PERATION
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 selections from which to
choose. The selections may be toggled by pressing the spacebar. Each time the
spacebar is pressed, a new selection appears. When the appropriate choice appears,
press Enter. In most cases, the new selection does not take effect until Enter is
pressed.
Fields enclosed in parenthesis ( ) are manipulated by one of the following two
methods:
✦ Pressing Enter on such fields as (Reset) and (Start Test) execute the function.
✦ 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. Characters 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 as well as
accepting typed input. Other fields are range checked, where the user cannot exit
the screen with an illegal value set.
Any of the screens may be redisplayed or refreshed by pressing Control + U.
Main Menu
Screen The Main Menu screen (Figure 4-2) lists the user-accessible functional menus. To
activate any menu, highlight the desired selection and press Enter. This menu and
any subsequent menu may be exited by pressing Escape. If the Main Menu is
exited, the terminal interface program terminates and hangs up the modem. This is
a valid way to end a user session. If any other menu is exited, the user is returned
to the previous screen.
The menu structure (Figure 4-3) shows all the screens accessible from the Main
Menu.
