You
can also send characters
directly without
inserting
them
in
the
text or showing
them on the screen.
Hold
[USE FRONT]
and
[SHlFTl,
press and release
[SEND
CONTROL],
then release [SHIFT].
The
characters
you
type
while continuing to hold
[USE
FBONT]
will
be
sent
when you
release
[USE FRONT]
but
will
not
be
dis-
played or
entered
in your text. This is useful
for
sending
passwords and other sensitive information.
If you
use
[SEND]
without
frst
establishing
a
connection
to
another machine,
the Cat
will
automatically use
the
PHONE command
and attempt
to establish
a
connection
for you.
It will
keep
trying until
the
automatic timer runs
out, and then hang up. Pressing any
key
will
also cause
it
to hang
up.
IUNDOI has
no effect on
[SEND].
Communications Between Cats
When you
send
text
Cat-to-Cat,
everything
is
transmitted:
words,
paragraphs,
pages,
boldface and underlining, cal-
culations and
their underlying
expressions,
margins,
in-
dents, and other features
of paragraph formatting.
When
the
connection
is
established and the Cat
determines
that
it
is talking to another Cat,
[SEND]
will
automatically
adjust
for
Cat-to-Cat communication.
If
you
are
commu-
nicating
with
another Cat via the serial
port,
use [SETUP]
and go to the
Serial
Port
Connection
screen.
Move down
the
list
to the
Communications mode line
and select
Cat-
to-Cat.
Communications Between Cats
and Other Devices
When sending
text to devices other than the Cat,
Half-
duplex or
Full-duplex
must
be
selected on
the
Commu-
nications mode line
of
the
Internal
Modem
Setup
screen.
If
you
are unsure
which to
use,
full-duplex
will
work
correctly most
of
the
time.
Some systems
require special characters
at
the end
of
each
line,
such
as a
return
(CR),
or
a
retum
and
a
line feed
(CV
LF).
A
return moves the cursor
to the left
edge
of
the
screen;
a
line
feed moves the cursor down one
line.
[SETUP]
allows you to
select
either
of
these, or
None
(no
line-end
character at
all).
If
you
select
CR or CR/LF
as
the
line ending, and the Cat
is
communicating with non-Catdevices
such
as
computers
or
data
services,
it
sends
only
the
surface text. Tab charac-
ters, margins, and indents are
replaced
with
space
charac-
ters.
This
is
not
done
if
the
highlight
does
not include the
first
character on the
line.
