Radio Shack TRS-80 Modem II - Page 18

Automatic
Mode
Automatic
Mode
Operation
allows you
to
leave your
Modem
and
Computer
"unattended"
and
the
Modem
II will
automatically
dial
or
answer the
phone.
This is
useful
for many
reasons,
foremost
among
them
being the
Modem
II
automatically
can
dial
numbers at
night when
the
phone rates
are
cheaper,
transfer
information
to
another
computer,
and
then hang-up
the
phone.
The
Modem
II has
both
AUTO/ANSwer
(for
answering)
and
AUTO/ORIGinate
(for
dialing).
AUTO/ANSwer
Mode
Operation
AUTO/ANSwer
Mode
can be
used in
conjunction
with
MANual
dialing or
AUTOmatic
dialing.
For
example, if
you and
another
person
wish to
communicate
using
VIDTEX
and
you've
previously
decided on
who
will be
ORIGinating
the
call and
who
will be
ANSwering it,
you
may
want
to use
AUTO/ANS.
In
the
following
example, you
will
AUTO/ANSwer
the
phone;
the
other person
will
MANually
ORIGinate
(dial) the
phone.
To
use
AUTO/ANS:
1. Be
sure both Modem
IPs
FORCE
DTR
Switches
are
set
to ON.
2. The
other
person
should set
his/her
Modem
Switches to:

4. The
other
person
should dial
your phone
number.
When your phone
rings, do not
pick up the
received.
After one
or
two rings, the
Modem
should seize the
phone lines
(and ON, OH,
and
TR
Lights
should go ON).
