Transmitting Data
When
you are ready
to
send
the
Information
on
the
screen
to
the
computer, depress
the
SHIFT
key
and, while holding
it
down, depress
the
XMIT
key.
This
will
cause a transmit
symbol
to
appear on
the
screen which
indicates point of
transmission.
(The
SHIFT
key
is
used
with
XMIT, PRINT,
CLEAR,
and
CLR/FG
to
prevent accidental transmission or
clearing
of
data being
prepared
on
the
screen.
)
The
cursor
will
return
to the
"home"
position
or
to the line
following
the last
transmit
symbol and
begin
to
transmit
all
foreground
data.
The cursor
will
scan each
line
(assuming
a
multiple
line
entry)
until
it
senses
a carriage return or end-of-line and
will
go on
to
the next
line until
it
returns
to the
transmit
symbol.
It
will
then
send a
CR
or
EOT
(selectable)
symbol
to
the
computer
and
reposition to
the
beginning
of the
next
line
for
a response
from
the
computer or
a
new
operator
entry.
4.
Clearing
the
Screen
Depress
the
SHIFT key and while
holding
it
down, depress
the
CLR
key.
This
will
clear
the
screen and automatically
"home"
the
cursor
(first
character
position of
first
line).
5.
Background/ Foreground
When
in
Batch
mode, data appears on
the
screen
of the
Hazcltinc
2000
in
background
(dim)
and foreground (bright) intensity.
Unless
specified
otherwise under
"Applications", page
16,
data received
from
the
computer
will
be
in
background
(protected),
while data
that is
entered by
the
operator
is in
foreground
(unprotected).
ONLY DATA
IN
FOREGROUND
(BRIGHT)
INTENSITY
CAN BE EDITED
BY THE
OPERATOR.
This prevents
the
operator from accidentally
destroying
infor-
mation from
the
computer such as
a
format and
necessitating
its
regeneration.
By using
the
CLR/FG
key
in
the
same manner
as
the
CLR
key,
the
operator
is
able
to
clear the
screen
of
only
foreground
data.
This
is
extremely
useful
in
an
application
such as re-
petitive
form
fill-out.
When
using
Background/ Foreground
in
setting
up
a
form,
protected
fields

the
screen
