Troubleshooting

 

 

If

 

you

 

don’t

 

get

 

an

 

OK

,

 

the

 

problem

 

may

 

still

 

be

 

in

 

the

 

communication

 

software.

 

Make

 

sure

 

you

 

have

 

done

 

whatever

 

is

 

necessary

 

in

 

your

 

software

 

to

 

make

 

a

 

port

 

connection.

 

Not

 

all

 

communication

 

programs

 

connect

 

to

 

the

 

COM

 

port

 

automatically.

 

Some

 

connect

 

when

 

the

 

software

 

loads

 

and

 

remain

 

connected

 

until

 

the

 

program

 

terminates.

 

Others

 

can

 

disconnect

 

without

 

exiting

 

the

 

program.

 

The

 

modem’s

 

TR

 

indicator

 

lights

 

to

 

show

 

that

 

the

 

software

 

has

 

taken

 

control

 

of

 

the

 

modem

 

through

 

the

 

COM

 

port.

 

 

Your

 

communication

 

software

 

settings

 

may

 

not

 

match

 

the

 

physical

 

port

 

to

 

which

 

the

 

modem

 

is

 

connected.

 

The

 

serial

 

cable

 

might

 

be

 

plugged

 

into

 

the

 

wrong

 

connector—check

 

your

 

computer

 

documentation

 

to

 

make

 

sure.

 

Or

 

you

 

might

 

have

 

selected

 

a

 

COM

 

port

 

in

 

your

 

software

 

other

 

than

 

the

 

one

 

the

 

modem

 

is

 

physically

 

connected

 

to—compare

 

the

 

settings

 

in

 

your

 

software

 

to

 

the

 

physical

 

connection.

 

 

If

 

the

 

modem

 

is

 

on,

 

the

 

cable

 

is

 

plugged

 

into

 

the

 

correct

 

port,

 

the

 

communication

 

software

 

is

 

configured

 

correctly,

 

and

 

you

 

still

 

don’t

 

get

 

an

 

OK

,

 

the

 

fault

 

might

 

be

 

in

 

the

 

serial

 

cable.

 

Make

 

sure

 

it

 

is

 

firmly

 

connected

 

at

 

both

 

ends.

 

 

Is

 

this

 

the

 

first

 

time

 

you

 

have

 

used

 

the

 

cable?

 

If

 

so,

 

it

 

may

 

not

 

be

 

wired

 

correctly.

 

Check

 

the

 

cable

 

description

 

on

 

the

 

packaging

 

to

 

make

 

sure

 

the

 

cable

 

is

 

the

 

right

 

one

 

for

 

your

 

computer.

 

 

Peripheral

 

expansion

 

cards,

 

such

 

as

 

sound

 

and

 

game

 

cards,

 

might

 

include

 

a

 

serial

 

port

 

preconfigured

 

as

 

COM1

 

or

 

COM2.

 

The

 

extra

 

serial

 

port,

 

or

 

the

 

card

 

itself,

 

may

 

use

 

the

 

same

 

COM

 

port,

 

memory

 

address,

 

or

 

interrupt

 

request

 

(IRQ)

 

as

 

your

 

communication

 

port.

 

Be

 

sure

 

to

 

disable

 

any

 

unused

 

ports.

 

 

The

 

serial

 

port

 

might

 

be

 

defective.

 

If

 

you

 

have

 

another

 

serial

 

port,

 

install

 

the

 

modem

 

on

 

it,

 

change

 

the

 

COM

 

port

 

setting

 

in

 

your

 

software,

 

and

 

try

 

again.

 

 

The

 

modem

 

might

 

have

 

a

 

problem

 

beyond

 

the

 

scope

 

of

 

this

 

user

 

guide.

 

If

 

you

 

have

 

another

 

Multi

Tech

 

modem,

 

try

 

swapping

 

modems.

  

If

 

the

 

problem

 

goes

 

away,

 

the

 

first

 

modem

 

is

 

possibly

 

defective.

  

The

 

Modem

 

Cannot

 

Connect

 

When

 

Dialing

 

There

 

can

 

be

 

several

 

reasons

 

the

 

modem

 

fails

 

to

 

make

 

a

 

connection.

 

Possibilities

 

include

 

 

lack

 

of

 

a

 

physical

 

connection

 

to

 

the

 

telephone

 

line.

 

 

a

 

wrong

 

dial

 

tone.

 

 

a

 

busy

 

signal.

 

 

a

 

wrong

 

number.

 

 

no

 

modem

 

at

 

the

 

other

 

end.

 

 

a

 

faulty

 

modem,

 

computer,

 

or

 

software

 

at

 

the

 

other

 

end.

 

 

incompatibility

 

between

 

modems

 

 

poor

 

line

 

conditions.

 

You

 

can

 

narrow

 

the

 

list

 

of

 

possibilities

 

by

 

using

 

extended

 

result

 

codes.

 

Extended

 

result

 

codes

 

are

 

enabled

 

by

 

default.

 

If

 

they

 

have

 

been

 

disabled,

 

include

 

V1X4

 

in

 

the

 

modem’s

 

initialization

 

string,

 

or

 

in

 

terminal

 

mode

 

enter

 

ATV1X4

 

and

 

press

 

E

NTER

.

 

When

 

you

 

dial

 

again,

 

the

 

modem

 

reports

 

the

 

call’s

 

progress.

 

 

If

 

the

 

modem

 

reports

 

NO

 

DIALTONE

,

 

check

 

that

 

the

 

modem’s

 

telephone

 

line

 

cable

 

is

 

connected

 

to

 

both

 

the

 

modem’s

 

LINE

 

jack

 

(not

 

the

 

PHONE

 

jack)

 

and

 

the

 

telephone

 

wall

 

jack.

 

If

 

the

 

cable

 

looks

 

secure,

 

try

 

replacing

 

it.

 

If

 

that

 

doesn’t

 

work,

 

the

 

problem

 

might

 

be

 

in

 

your

 

building’s

 

telephone

 

installation.

 

To

 

test

 

the

 

building

 

installation,

 

plug

 

a

 

telephone

 

into

 

your

 

modem’s

 

telephone

 

wall

 

jack

 

and

 

listen

 

for

 

a

 

dial

 

tone.

 

If

 

you

 

hear

 

a

 

dial

 

tone,

 

your

 

modem

 

might

 

be

 

installed

 

behind

 

a

 

corporate

 

phone

 

system

 

(PBX)

 

with

 

an

 

internal

 

dial

 

tone

 

that

 

sounds

 

different

 

from

 

the

 

normal

 

dial

 

tone.

 

In

 

that

 

case,

 

the

 

modem

 

might

 

not

 

recognize

 

the

 

dial

 

tone

 

and

 

might

 

treat

 

it

 

as

 

an

 

error.

 

Check

 

your

 

PBX

 

manual

 

to

 

see

 

if

 

you

 

can

 

change

 

the

 

internal

 

dial

 

tone.

 

If

 

you

 

can’t,

 

change

 

your

 

modem’s

 

initialization

 

string

 

to

 

replace

 

X4

 

with

 

X3

,

 

which

 

will

 

cause

 

the

 

modem

 

to

 

ignore

 

dial

 

tones.
