to the
numeral keys

7, 8, 9, and 0.
The
non-numeral symbols
#
and
*
are dialed as
tones
corresponding to
the
extended tone-dial keypad. A comma
(,)
causes a
l/2-second pause
in

Qtulse
dialing
is
characteristic
of
phones
with
circular
dials, rather
than
push-button
keys).
Two
signs appear on the
ruler while
the Cat is
dialing:
the
telecommunication sign (the
outline of
a
telephone hand-
set) and the
word DIAL.
Once the
number
is
dialed,
the
Cat waits
for
a
carrier signal.
A carrier
srgnal
is
a tone
indicating that
another modem-equipped
machine
has
picked
up the
line.
The amount
of time
the
Cat
waits for
a
carrier signal can
be adjusted
with
[SETUPI.
If
the Cat hears
a
carrier signal, it automatically
establishes
a
connection
and
gives you
a
confirm
tone.
Aconfirm
tone
is
a
low-pitched
beep. The ruler displays
3fi)
or
12fi) (rate
of transmission) next to the telecommunication
sign.
This
indicates
the baud rate, the speed
at
which signals
are sent.
If
the Cat
doesn't
hear
a
carrier
signal before
its
timer runs
out, it
hangs
up the
line.
When the Cat
detects
a
carrier,
it
mutes your telephone receiver in order
to avoid communi-
cation errors
due to noise
from your
telephone.
You
can
only
hear the
carrier
signal
for
a second
or two
if
you
are
listening in.
A
spoken telephone conversation between people
will
not
have
a
carrier.
so
the modem is not involved.
