### SET-UP Mode
From "PART 2: SET-UP MODE", p. 2-6, of the VT100 Technical Manual (July 1982):
> Unlike most terminals, the VT100 does not use switches or jumpers to individually turn the built-in terminal features on
or off. Instead, the VT100 uses a nonvolatile memory (NVR) that always remembers what features have been selected, as if a
swiitch had been set.
> Selection and storage of built-in terminal features is performed in a special mode of operation called SET-UP mode.
When you enter SET-UP mode, the status of features stored in temporary memory shows on the screen. You can then change the
features and store any new feature selections either temporarily, by leaving SET-UP mode; or on a fixed basis, by performing
a Save operation. In either case, terminal operation reflects the new feature selection. If a recall operation is performed,
or the terminal is reset, or terminal power is turned off, all temporary feature settings are replaced by features that have
been stored on a fixed basis.
> ### SET-UP Features
> SET-UP mode provides two brief summaries of the current feature status. The first presentation - SET-UP A - displays
the location of tab stops set and a visual ruler that numbers each character position on the line. The second presentation -
SET-UP B - summarizes the status of the other terminal features.
> **SET-UP A** - To enter SET-UP A, press the **SET-UP** key. The display has a presentation similar to Figure 2-3. The bottom
line of the display consists of a "ruler" that numbers each character position available on a line. Each tab stop is shown by
a "T" above the ruler. If the tab stop(s) set are those desired, you may exit **SET-UP** mode by pressing the SET-UP key again
or you may now change the tabs to meet your requirements.
> **SET-UP B** - SET-UP B mode may only be entered from SET-UP A mode. To enter SET-UP B, from SET-UP A press the **5** key on
the main keyboard. The display looks like Figure 2-4. Figure 2-5 summarizes the SET-UP B presentation. This summary allows you
to quickly determine what features are enabled. For additional information on a feature refer to in Part 3, SET-UP Feature
Definitions.
