INTRODUCTION

Modems are everywhere these days, tying together millions of computers via the telephone
lines. A modem can also be found at the heart of each TTY (text telephone) used by people
who are deaf or hard of hearing. But not all modems are alike, nor can they all talk to
each other. Computer modems use ASCII code and most TTYs use Baudot code. Without
the Intele–Modem, these codes are not compatible.

The Intele–Modem’s specialty is allowing computers to talk to TTYs. It listens to one type
of code and converts it to the other. The Intele-Modem can also send and receive in ASCII
code. Your Intele–Modem can communicate with any 110- or 300-baud ASCII device,
including TTYs which use ASCII code. (The baud rate is how fast a code travels over the
phone line.) In Baudot, the Intele-Modem can use either the American standard of 45 baud
or 50 baud.

The Intele-Modem is Hayes-compatible. This means you can use Hayes commands (also
called AT commands) to control your modem. The Intele–Menu command set makes it easy
to dial numbers, answer incoming calls, set up Auto-Answer, or change any of the
Intele–Modem’s settings.

The Intele–Modem also features automatic detection of both Baudot and ASCII calls. It
works with commercially available communications and bulletin board software. Front
panel lights indicate the current operating mode and line status. Screen messages signal
call progress by telling you if there’s a dial tone, and if the other phone is busy or if it’s
ringing.

In many situations, your communication software will take care of making your calls. You
won’t need to send commands directly to your modem. However, when you do need to
control the modem, you have your choice: Ultratec’s Intele–Menu commands or standard
Hayes commands.

HOW TO SET UP YOUR INTELE–MODEM

Equipment you need ________________________________________

The place where you set up your computer and modem should have several electrical
outlets and a telephone wall jack within five or six feet.

CAUTION: The Intele–Modem is designed for standard telephone lines, and it
will not work with a computerized telephone system such as a PBX.
Connecting the modem to a non-standard phone line may damage your
telephone system or Intele–Modem, and will void the warranty. If you have
questions, contact your phone system installer.

The Intele–Modem.

The Intele–Modem comes with AC power and telephone cords.

A personal computer or a computer terminal or workstation.

You can use an IBM or IBM-compatible, Macintosh or other brand of computer. You can
also use a terminal designed for connection to a mainframe or network, as long as you
have the right software. The serial com port setting must be: 300 BAUD, 8N1, No Flow
Control (No Software Flow Control).

A telephone line.

Don’t use a party line or a line that’s part of a multiple-phone system, such as a PBX. Use
a standard, analog telephone line. A telephone is optional.

A communications software program.

There are many different programs that will work. Any program that provides for
“terminal emulation” will do. If in doubt, ask your computer store or microcomputer user
group for the software that works best with your computer.

A cable to connect your Intele–Modem to your computer.

You need a cable with a connector for the modem on one end and the right connector for
your computer on the other. Computers have many different kinds of connectors. Standard
cables for IBM-compatible and Macintosh computers are available from Ultratec.

Setting up _________________________________________________

1. Be sure the Intele–Modem “ON” switch is pushed to the right (the off
position). The switch is on the back panel. Plug the AC power cord into the
PWR (power) jack. Plug the other end into an electrical outlet.

2. Plug one end of the Intele–Modem computer cable into the RS-232C port on
the back of your Intele–Modem. Plug the other end into the serial port of
your computer (sometimes called the RS–232C port).

3. Telephone hook-up. Plug the telephone cord into either one of the telephone
jacks on the back of the Intele–Modem. Plug the other end of the cord into a
telephone wall jack. To connect a phone to the same line, plug the telephone
cord into the second jack on the Intele–Modem’s back panel.

HOW TO USE YOUR INTELE–MODEM

1. Connect all the hardware.

2. Turn on your computer and load your communications software. If you need
more information on these first two steps, see page 3.

3. Turn on your Intele–Modem.

4. Use your software to dial or answer a call. Your software will also allow you
to change settings that determine how the modem operates. See your
communications software instructions for more information.

The rest of the information in this guide is for those who need to directly control their
modem. To do so, follow the above steps to enter terminal mode. Then, choose the
Intele–Menu command set or the Hayes command set. You must use one command set or
the other—you can’t intermix the two.

Intele–Menu command set ___________________________________

This is a special set of commands created by Ultratec to simplify controlling your
Intele–Modem. When you type your computer’s Escape Key followed by the Spacebar after
turning on the modem, the modem will display this line on your computer monitor:

Command (Press ? for help):

All commands are issued from this Command Line (see page 5).

Hayes command set _________________________________________

These are standard commands used by most computer modems. Ultratec has added
several special commands for use with Baudot code (see page 14).

Talking to the modem vs. another computer or TTY______________

No matter which command set you use, your Intele–Modem operates in two modes.
Issuing commands is done in command mode, whereas the actual communication with
another person takes place in on-line mode.

Command mode ____________________________________________

In command mode your modem receives instructions from you via the computer keyboard.
Sometimes command mode is referred to as “local” or “off-line” mode because you are
talking to the modem itself, rather than to another computer or TTY.

On-line mode_______________________________________________

In on-line mode, your modem serves as a bridge between your computer and another
computer or TTY, transmitting the messages that you and the other person type back and
forth.

How to switch between modes________________________________

How you switch modes depends on which command set you’re using. If you’ve using
Intele–Menu commands, use the Escape Key to enter command mode. After you’ve typed
the command you want, use the Enter Key to return to on-line mode.

If you’re using the Hayes Command Set, use the “escape sequence” to enter command
mode. This is the escape sequence: wait until no characters have been typed for at least
one second, type the + Key three times in a row (like this: +++), and then wait another
second. When you’re in command mode, switch back to on-line mode by issuing an ATO
command.

CALLING WITH INTELE–MENU COMMANDS

General procedure __________________________________________

Set up your hardware, turn on the computer and modem, and load your communications
software. Enter terminal mode. The communications program instructions will show you
how to get into terminal mode (sometimes called “talk” or “on-line” mode).

1. Press the Escape Key and then the Spacebar to enter command mode. The

Intele–Modem will display the following prompt on your computer screen:

Command (Press ? for help):

2. Type the letter or number for the command you want (or type ? to see the

Help Menu). Commands are described starting on page 9.

3. Press the Enter Key to return to on-line mode and carry on your

conversation.

If you don’t see the Command Line when you press the Escape Key and the Spacebar, try
typing ATZ first. See the Problems and Solutions section on page 21 for more information.

Step-by-step instructions_____________________________________

Modem settings

When you follow these instructions, you will be using the following modem settings:

• Automatic communication mode. The modem will use either ASCII or

Baudot code, depending on what it receives from the other computer or TTY.

• Half-duplex

• Pulse dialing

Instructions

1. Turn on your computer.

2. Start up your communications software.

7. Press the Enter Key. The modem will dial the number. The OH (Off-hook)
and SIG (Signal) lights will go on.

If the modem can’t dial the number, you’ll see NO DIAL TONE on your
screen. The modem will hang up and the Command Line will reappear on
the screen.

If the line is busy, the modem will hang up and display BUSY on the screen.
If dialing succeeds, you’ll see RINGING on the screen. When the number

answers, you’ll see one of two responses on your screen:
CONNECT - the modem has connected to another computer or TTY and is using

ASCII code. The CD (carrier detect), ASC (ASCII code), and either the HI or LO
lights will all come on.

CONNECT TTY - the modem has connected to a TTY and the TTY has sent a
message in Baudot code. The BDT, OH, and LO or HI lights will stay on. The
SIG light will go on when either you or the caller type

.

If the only response you see is RINGING, no one is answering. Hang up by
pressing the Escape Key followed by the H Command. Return to on-line mode by
pressing the Enter Key.

8. When you see one of the connect messages, go ahead and start your
conversation. You’ll see the RXD (Receive Data) and TXD (Transmit Data) lights
flashing as you send and receive messages in ASCII code. If you’re using Baudot
code, the SIG (Signal) light will also flash.

If you don’t see what you’re typing on the computer monitor, change your duplex
setting to half-duplex. Type the Escape Key, then the F Command and the Enter
Key.

9. To hang up when you’re done, press the Escape Key and H. You can also hang up
by turning off your Intele–Modem.

Special situations ___________________________________________

The above description assumes that your modem is in automatic mode (set with the 1
Command). If the modem is set to ASCII, and no carrier signal is detected after 30 seconds, you
will read NO CARRIER and your modem will hang up.

The description also assumes that your modem is set to half duplex. If you see double
characters on the screen when you type (lliikkee tthhiiss), change to full duplex.
