Remote
Configuration
Configuring
the
modem
results
in
core
settings
that
allow
the
modem
to
function
properly
on
the
console
port
of
the
Cisco
router.
You
can
use
commands
described
in
this
section
to
remotely
call
into
the
MT9234ZBA
attached
to
the
console
port
with
another
modem.
Note:
Setting
country/region
configuration
and
turning
on
callback
security
cannot
be
done
remotely.
Nor
can
all
commands
be
executed
remotely
if
the
remote
modem
is
set
for
callback
security.
Remote
configuration
of
a
modem
configured
this
way
is
not
recommended.
1.
Establish
a
data
connection
with
a
remote
MT9234ZBA
modem.
2.
Send
three
remote
configuration
escape
characters
followed
by
AT
and
the
setup
password,
and
then
press
E
NTER
.
Example:
%%%ATMTSMODEM
.
You
have
four
tries
to
enter
the
correct
password
before
being
disconnected.
If
the
password
is
correct,
the
remote
modem
may
respond
with
OK.
Note:
If
the
modem
has
previously
been
configured
with
command
echo
off
and
result
codes
off,
it
may
be
difficult
to
determine
if
the
remote
modem
is
responding
to
commands.
The
ATI
command
can
be
used
for
this
purpose.
Even
with
echo
and
result
codes
off,
the
modem
will
respond
with
the
requested
ID
string
if
it
is
properly
receiving
the
command.
3.
You
can
now
send
AT
commands
to
configure
the
remote
modem.
4.
When
you
have
finished
configuring
the
remote
modem,
save
the
new
configuration
by
typing
AT&W0
<
CR
>,
then
type
ATO
<
CR
>
to
exit
remote
configuration.
You
can
then
break
the
connection
in
the
normal
way.
Note:
This
step
is
important
to
ensure
that
the
connection
is
broken
cleanly.
