Holding A Cat Conversation ６ - Canon Cat Reference Manual

Switching From Voice Communications
to Telecommunications
You can switch from voice communications
to
text
trans-
mission during
the same
call.
Use
[PHONE]
while you
are
on the
line. The Cat
will
start searching for
a
carrier signal
while
sending out
a
carrier
signal
of
its
own. Your partner
should use
[PHONE]
about
the
same
time
in
order to
establish a
connection.
If
he has
a
computer, he needs to
use the appropriate answer command
for his
equipment.
Switching From Telecommunications
to Voice Communications
If
you
are
sending text Cat-to-Cat or Cat-to-computer
and
wish
to
continue
the
call
voice-to-voice,
lift
your telephone
handset and
use
[PHONE].
This
will
cause
the Cat
to
tum
off
the modem and open the
phone line for
voice communica-
tions.
When the
Carrier
Signal Is Lost
The carrier signal is
used
to
transmit
text
between ma-
chines,
so
It
is present the entire time
the Cats are
commu-
nicating. The carrier
signal
will
be
lost when
your partner
uses [PHONE]
in order to switch to voice communications,
or when
a
data service hangs up
on
you
at the close
of
a
session.
When
the
carrier signal is lost,
the Cat beeps and
tries to
find
it
again.
[EXPLAIN]
will tell
you that
the
carrier
was
lost.
Ifthe
Cat cannot re-establish
a
connection after
a
few
seconds,
it
hangs up the
line. Note
that the
[SETUP]
timer
is not
triggered
under
these
circumstances.
You
have
just
a
few
seconds to
pick
up the phone
if
you want to talk to
your
partner.

If
you

Connection
screen
of
the

command,
[SEND]
will
send
the
text outthe serial port. The
serial

cable.
Amodem

a
device used to convert
text into
sound
signals that can be transmitted over phone lines
and de-
coded
by
a
Cat or
a
computer at the other end.
[SEND]
is
an autoextending
command:
If
the

use the command,
it
extends
automatically
as
if you
had
pressed both LEAP
keys, and
then the
command
is
carried out. The highlighted
text
will
be the area
covered in your
last leap, or typed
since
you last
pressed
both
LEAP
keys.
