computer
must
be
running
and

Setup
Multi
‐
Tech
modems
are
shipped
with
a
default
setup
password
(MTSMODEM).
Because
anyone
who
has
the
User
Guide
knows
the
default
setup
password,
you
should
change
the
password
and
possibly
also
the
remote
configuration
escape
character.
Changing
the
Setup
Password
1.
Open
a
data
communications
program
such
as
HyperTerminal.
2.
In
the
terminal
window,
type
AT#SMTSMODEM
(or
AT#S
xxxxxxxx
if
you
have
replaced
the
MTSMODEM
password
with
xxxxxxxx
)
and
press
E
NTER
.
The
modem
responds
with
OK
if
the
setup
password
is
correct,
and
ERROR
if
it
is
wrong.
3.
To
change
the
password,
type
AT#S=
xxxxxxxx
,
where
xxxxxxxx
stands
for
the
password,
and
then
press
E
NTER
.
The
password
can
include
any
keyboard
character,
and
can
be
up
to
eight
characters
long.
The
modem
responds
with
OK
.
CAUTION:
Passwords
are
case
‐
sensitive.
The
next
time
you
enter
the
password,
it
must
be
in
the
same
case
as
you
set
it
up.
4.
The
new
password
is
saved
automatically.
You
can
now
either
enter
more
AT
commands
or

the
data
communications
program.
The
