means
that the
Cat
will
use
the
same
rate
as
the
modem
it's talking to. This
is
almost always
the
choice
you
should select, since
it
allows
the Cat to
send
characters
at the
fastestpossible rate.
The other

forces the Cat to
work
at the
lower
rate
of
300
baud. This
may
be
useful
if
a
noisy
telephone
connection
produces errors
at
1200 baud.

Each
of
these
must
be
set
to
the
correct value
for
the data service
or

you
are
communicating
with.
Consult
your
data service
manual
or
ask

Communications
mode
Selects
the
way
in
which
Cat
signals
are sent
over
the
phone
line. If
you
want to
talk to
another
Cat,
select
Cat-to-Cat. If
your Cat is called by
another
Cat,
your
Cat
will
automatically
set
itself
up to
communicate
correctly.
If
you want to talk to a
data
service,
select
Full-duplex
or
Half-duplex
depending on
what
the data service
requires; your
data service manual
should
tell you which
is
correct.
If
you're not
sure,
try
Half-duplex. If
each
character
appears
doubled, switch
to
Full-duplex.
If
you
select
Cat-to-Cat, the Cat's internal
modem
is
automatically
set
to
the
correct
values. You
need
not (and
should
not)
change
any other
values
on the Internal
Modem
Setup
screen.

you
select

sends
back
the
phrase
Canon Cat

whenever
it
receives a
CON-
TROL-E character.
If
you
select
No,
the
Cat
ignores
a
CONTROL-E.
