rectangle
is
stored at the cursor location and the cursor advanced per the
Auto
CR/LF
rear panel switch. When HZ1500+ mode and Line
or
Page
Transmit mode are selected, data compression
will
be
accomplished in a
manner
identical
to
the
other
emulation modes. In these
cases
the
CR
code
will
not
be
stored, and thus
will
not
be
used
for
data compression.
4.12.2.3 Line Mode Transmission
When Line Mode
is
set, and transmission
is
initiated,
only
the data on the line specified
by
the cursor
will
be
transmitted. Data compression deletes
spaces
of
the last field and
only
those
spaces
from
the last character
to
the
end
of
the line. The start
of
Message
code,
if
any,
is
appended at the beginning
of
the
transmitted line.
Because
the
maximum
length
of
transmitted data
is
one line, the End
of
Line code (s),
if
any,
are
not
used
and the trans-
mission
is
terminated
with
the
End
of
Message
code (s).
When transmission ends, the cursor
is
placed at the left-hand margin
of
the
next
line. In
HZ1500+
mode, the cursor
is
placed in the
same
column, one line
below
the transmitted
line, except when the last line
has
been transmitted, when the cursor
will
be
placed at the
left
margin.
NOTE
If
the last line
is
transmitted
while
the terminal
is
in
Unprotect
mode and Scroll
mode, the screen
will
scroll-up one line.
4.12.2.4
Page
Mode Transmission
When
Page
mode
is
set, and transmission
is
initiated, all data on the screen
will
be
trans-
mitted.
(If
Protect mode
is
set,
only
the unprotected fields
will
be
transmitted).
Spaces
to
the
right
of
the last character on
each
line are suppressed, just
as
in Line mode. The
start
of
the
Message
code,
if
any,
is
appended
to
the beginning
of
the transmitted
page.
At
the end
of
each
line, the End
of
Line code
(s)
are appended. End
of
Message
codes
are appended
for
the last line.
4.12.2.5 Batch Mode Transmission
When Batch mode
is
set, and transmission
is
initiated,
all data
from
the beginning
of
the
line
following
the previous
transmit
symbol, up
to,
but
not
including the cursor location,
will
be
transmitted. The
transmit
symbol
is
a
full-intensity
solid rectangle (rub-out) which
is
stored on
the
screen
to
mark the end
of
transmission. A new
transmit
symbol
is
stored
at the end cursor
location
to
mark the new last
point
of
transmission and the cursor
is
advanced
to
the left-hand margin
of
the
next
line.
If
no
transmit
symbol
was
previously
on the screen, the transmission
will
occur
from
the
home position, up
to,
but
not
including
the
cu
rsor location. The Start
of
Message,
End
of
Line, and End
of
Message
codes
will
be
appended at
the
Start
of
Message,
End
of
Lines and End
of
Message
respectively provided
the
terminal
is
not
set
to
HZ1500+
mode. In
HZ1500+
Batch mode, the Start
of
Message
code
will
not
be
appended and the
only
End
of
Line code
is
the stored
CR
code
(if
any),
which
is
also used
for
data compression
as
described in section 4.12.2.2. The End
of
Message
code
is
still
initially
determined
by
rear panel switches just
as
in any
of
the
other
emulation modes.
