On
initial
power-up,
the
list
will
not
show
an
entry
for
PHONE
NO:.
The
10 bits-per-word
prompt
is
answered by
the
Modem
after receiv-
ing the
wake-up
command
code sequence.
When
you
use 7-bit
words,
the 10
bits
parameter shows
res (10
BITS/CHAR:Y).
Of
course,
an
8-bit
word
with
no
parity
is
a
10-bit
word
(if
you
count
the stop
and
start
bits).
If
you
have a
computer
(or
terminal)
which
transmits 8-bit
words and
a
parity
bit
{11
total
bits)
you
will receive
parity errors
from
the
DCM
213
(that
is,
if
it
locks
onto your
wake-up
sequence).
Each
line in
the
parameter
listing
is
terminated with a
carriage return
and
a line feed. If
your
serial
communications
software automatically
assumes another
carriage return
upon
reception
of a
line
feed code,
the
list
will
appear double-spaced.

In
manual
operation
mode, you can
control
what
the system does
by
manually
dialing
and
answering the
phone.
When
you want
the
DCM
212
to dial
a
phone number
or
answer
the
phone
for you,
set
the
DCM
212
to
automatic operation
mode.
In
this
mode,
the
DCM
212
dials
the
phone number you
store in
its
memory
or answers the
phone
when
someone
calls
you.
When
freshly
powered
on, the
DCM
212
defaults to
automatic
mode
operation.
To change
to
manual mode,
toggle the
manual/automatic
flag
by
pressing
(m)
for the
M
command. Then
press
(T)
to see the
status
of
this flag.
The
list
shows:
MANUAL M0DE:Y
"Yes, I'm
in
manual
mode."
Press (M)
again
and
the
list
changes
to:
MANUAL MODE
:

"I'm
in
automatic mode:'
Pressing the key again
changes the
parameter
setting to
manual
mode
again.
