Summary
BECOMING
FAMILIAR WITH
OPERATION
The
following
is
a
summary
of
what
to
expect
when
you
begin operating
your
4023
on
line
with
a
computer.
The 4023 communicates
with
a
computer
in
three
basic
configurations,
which
can be
summarized
as Direct,
Non-Formatted
display
(Buffer),
and
Formatted
display
(Buffer
Form
Fill-Out).
General
In
Direct
communication,
the
DIRECT/BUFFER
switch
is
set
to
DIRECT.
If
the
LOCAL/ON
LINE
switch
is
set
to
ON
LINE,
data
typed
from
the
keyboard
is
sent directly to
the
computer. However,
most
systems
provide an
"echo"
that
allows the
keyboard
entries to
be displayed
for
viewing
by
the
operator.
The
echoing
of transmitted data
occurs
so rapidly
that
it
gives
the impression of having occurred
immediately
when
the
key
was
pressed.
Direct
Mode
Editing
the
display
from
the
keyboard
serves
no purpose
in
Direct
communications,
because the
computer
has already received the informa-
tion.
However, most systems
provide
some
form
of
program
editing.
If
you
are
working
with
such
a
system, consult
your programmer
for
more
information.
