3.2.1.6 Performing a RESET Operation
The RESET operation
has
the
same
effect
as
powering-down then powering-up the terminal
and
is
used
to
run the self-test and return the SET-UP features
to
their
fixed states. This
operation
will
also clear the screen
of
any data. The RESET operation
is
performed per the
following:
1.
Enter SET-UP mode
2.
Depress the
DJ
key on the keyboard. The terminal
will
reset and return
to
all initialized parameters and fixed SET-UP features.
3.2.2 SET-UP Feature
Definitions
This section describes
each
SET-UP feature and the
effect
of
each
feature on the

3.2.2.1 Line/Local
On-line
or
local operation may
be
selected in either SET-UP A
or
SET-UP B mode by
depressing the

key. On-line operation
is
indicated
by
the

send

from
the host
computer.
Local operation
is
indicated
by
the
illumination
of
the
LOCAL
LED. When in Local, the
terminal
is
electrically disconnected
from
the host computer.
Any

3.2.2.2 Characters
Per
Line
The
VISUAL
100 may display a screen
format
of
either 24 lines
of
80 characters,
or
24 lines
of
132 characters. When changing between the
80/132
column formats, the contents
of
the screen
are
destroyed.
Characters per line may also
be
changed
by
the host,
see
Section 5.3.2.12.
NOTE
If
double
width
characters are used, the number
of
characters per line
is
halved i.e., a 132 column
format
used
in conjunction
with
double
width
characters provides
for
66
double-width characters per line.
