is the software revision. Information is displayed for the near end unit (connected
directly to the terminal) on the top line, and for the far end unit (connected to the
network interface) on the second line. Far end information is displayed only when

this information when contacting the factory with inquiries.

currently accessible such as MAIN or PERFORMANCE.
Messages Diagnostic messages may be displayed at the bottom of the screen.
Cursor The terminal interface uses a highlighted cursor to make selections from menus
and select fields within screens. The cursor is moved in different ways, depending
on the terminal emulation program used. Most programs use the Tab and
Shift+Tab keys. Other programs use the arrow keys. For keyboards which do not
have these standard keys or have only some of them, an alternate set of cursor
control commands is provided (Table 4-1). Each command is performed by
pressing a letter key while holding down the Control key. Alternate commands
may be freely mixed with the keyboard commands at your discretion.
Field Types Each screen is made up of fields. The two basic field types are user-selectable and
display-only. Fields without brackets or parenthesis are display-only. They cannot
be changed on the screen.
If the highlighted cursor can be moved to a field, it is a user selectable field. User
selectable fields allow for changes to be made or commands to be executed. Most
user selectable fields are enclosed in brackets or parentheses.
