What ModemLink Can Do For You

elcome to the fascinating world of telecommunications. Your ATARI

1030 Direct-Connect Modem with its built-in ModemLink telecom-

munications program places an almost infinite variety of information

w

and financial services-at your command.

A telephone call connects your ATARI Home Computer to information
utilities where you can shop, play interactive computer games, make airline

reservations .... Send and receive electronic mail. ... Or make new friends

on any of the hundreds of local bulletin board systems operated by home com-

puter owners like yourself .... All from the comfort of your home.

This owner's guide provides easy-to-follow setup procedures for the ATARI

1030 Direct-Connect Modem, plus instructions for loading ModemLink into your
computer and dialing a call from your computer keyboard. You'll also find
descriptions of the HELP features that make Modeml.ink convenient to use,
answers to many frequently asked questions, and helpful definitions that will
start any beginner on the way to becoming an expert in data communications.

Hooking Up Your ATARI 1030 Direct-Connect Modem

Plug the I/O data cord that
came with your modem into
either of the serial I/O ports on
the back of the modem. Plug the
other end into a serial I/O port
on your computer or peripheral
(an ATARI
Recorder should not be con-
nected to your system when
you're using your ATARI
Direct-Connect Modem with
ModemLink).

Starting U p With Modem Link

If you have an ATARI400™, ATARI800™, or ATARI

1200XLTMComputer, ModemLink loads automatically into
your computer -all you need to do is turn on your
modem, then turn on your computer. To load ModemLink
when you have a language cartridge-such as ATh.RI
BASIC or PILOT- plugged into your computer, first turn
on your modem, then the computer; then type DOS and
press

If you have an ATARI600XLTMor ATARI800XLTMCom-
puter with built-in BASIC, first turn on your modem,
then-while holding down the
computer to load Modemhink. If your computer is
already on and you want to switch from BASIC to
ModemLink-or if you have a PILOT cartridge plugged
into your computer-type DOS and press
Modeml.ink.

When the ModemLink start-up screen appears, make
your selection by typing one of the numbers shown in in-
verse video (blue characters on a white background),

Choosing Between Pulse and Tone Dialing

Before you use your computer's keyboard to dial a
call, make sure you've selected the correct dialing pro-
tocol-tone (push-button) or pulse (rotary)-for your
phone. To select tone (push-button) dialing, type 4. Type
4 again to return to pulse (rotary) dialing.

Switching from Origin ate to Answer

When you turn it on, your ATARI 1030Direct-Connect
Modem is in the ORIGINATE mode-that is, ready to
transmit and receive data at a predetermined set of fre-
quencies (these frequencies correspond to the ones used
by answering modems to receive and send data).

When you're calling a service, your modem should re-
main in ORIGINATE-the service's modem is always in
the ANSWER mode. But when you're exchanging data
with another individual computer owner, one modem
must be set to ORIGINATE and the other to ANSWER in
order for the modems to communicate.

Follow these steps to switch your modem to ANSWER.

1. Manually place or answer a call as usual-it doesn't
matter who dials it-and establish voice contact.

2. Have the other modem placed in ORIGINATE, then
connected to the phone line (the other modem will

probably connect to the line when the other caller
replaces the handset in the cradle; some modems,

however, have a switch that must be activated to
place them on line).

3. Type 3 to select ANSWER-CALL RECEIVED.
ModemLink responds by sending a carrier tone,

then waiting for an answering carrier tone from the

other modem.

4. Return your telephone handset to its cradle when
ModemLink displays the message PLEASE HANG
UP PHONE, WAITING FOR CARRIERon your TV
screen. You'll know your modem is receiving a car-
rier tone from the other modem when the READY in-
dicator on the front of your modem lights up. You're
now ready to exchange information.

To return to ORIGINATE, press the

key on

your computer.

ModemLink's HELP features make it versatile and easy
to use when you're on line with another, computer
system. They let you turn your printer on or off, change

When you first turn on your ATARI 1030 Direct-Connect
Modem, it places all incoming information in your com-
puter's memory buffer. Eventually, the computer's
memory buffer will fill up, and the oldest information
received will be replaced by new data as it comes in;
the message NEWEST DATA RECEIVED appears above
the old information to separate it from new data.

But ModemLink lets you store a certain amount of in-
coming information in the memory buffer, so you can
read it again. How much information your memory buffer
can store depends on how much RAM (random-access
memory) your computer has.

To store data in the buffer, you must first switch to

received the information you want to store, turn the
memory buffer off by pressing
Your modem will continue to accept new information
and display it on your TV screen, but data won't be
added to the buffer until you turn it back on again,
You can add to the buffer as often as you wish-until
the buffer is full, of course-by turning the memory
buffer on and off as necessary,
2, You can store all incoming information until the
memory buffer fills up completely, When the buffer is
full, the message MEMORY BUFFER FULL-PRESS
SPACE BAR TO CONTINUE appears on your screen,
and your modem sends a "stop transmission" signal to
the other modem (your modem won't accept new data
even when the other modem ignores the "stop
transmission" signal and continues to transmit),

Then you can either press the space bar (and erase the
contents of the memory buffer) or turn the memory buffer
off (and retain the entire contents of the buffer),

Pressing the space bar empties the buffer, sends a "start
transmission" signal to the other modem, and lets
ModemLink fill up the memory buffer.

Turning the memory buffer off sends a "start transmis-

sion" signal to the other modem and lets your modem

Question:

ModemLink receives a carrier tone, but the
modem's READY light doesn't light up. What should I
do?

Answe r:

The modems may not be able to communicate
with each other because they're in the same mode-that
is, both in ORIGINATE or ANSWER-or you may have a
bad connection, or the carrier signal may be too weak.

Handshaking:

An exchange of predetermined signals
that takes place between two modems (and their respec-

at 300 bps, full-duplex transmission-can "shake hands"
and exchange data.
