Xerox 3270 User Manual

When your settings have been downloaded to the temporary mem-
ory through the FSL Functions, you may wish to save them perma-
nently for future uses. For this purpose, special commands can be
used.

Once the settings have been saved, the  converter will read them each
time power is turned on, or when it registers a special command in the
datastream.

Section 3.1. The Three Levels of Settings and Section 3.3  Action at
Power On explain the interaction of the three levels of settings and
the actions taking place when power is turned on.

Section 3.2. Commands for Storing and Restoring Settings describes
the commands that manipulate the temporary and the permanent
memory areas. Section 3.4. Restricting Access explains the special
facility which enables you to restrict access to the temporary and/or
the permanent memory areas.

The converter stores settings on three different levels:

1.

The Factory Default Area

2.

The Permanent Memory

3.

The Temporary Memory

The temporary memory settings constitute the first level. When the
converter operates, it always retrieves information from the tem-
porary memory area to determine the next action required.

The factory default and permanent memory areas are used only
when power is turned on, or when a specified command to read them
is registered.
