immediately.
1.2 What else you need
To complete your data communication system, you will need the following items:
lSome type of communication software, if not included.
lAn optional telephone set ( you do not need to use a telephone with your modem ).
1.3 Installing the modem
Your modem fits neatly under most standard desk-top telephone. You should place your
modem near a 110 or 220 VAC power source (such as a wall outlet). The distance
between the modem and your computer, terminal, or printer is determined by the length of
your RS-232-C cable.
Be sure you can clearly see the panel LEDs, reach the ON/OFF switch on the back panel,
and hear the built-in speaker when you dial calls or the speakerphone is in use.
1.4 Prerequisites
When connecting your modem to a computer, you will need:
lAn available RS-232-C serial port.

5634RCS User’s Manual

1.7 Connecting to your telephone
Your modem is so convenient. It provides a second modular telephone jack that lets you
connect your telephone to the same telephone line the modem is using. This lets you
manually dial data calls or make voice calls when you are not using your modem.
Use the following procedure to connect your telephone to your modem:
1. Connect the telephone's modular cord into the PHONE jack on the back of your
modem (see figure 1-1).
2. Lift your telephone's handset and listen for a dial tone.
1.8 Connecting to an AC outlet
Use the following procedure to connect your modem to an AC outlet:
1. Insert the supplied power cable into the round AC-IN connector next to the POWER
switch on the back of the modem (see figure 1-1).
2. Plug the end with the power pack into either a 110 or 220 VAC outlet.
3. Turn the POWER switch to ON position, then the MR LED goes on.
4. Turn on the computer or terminal connected to the modem.
1.9 Using a external MIC and speaker1
If you want to use an external MIC or speaker instead of using the built-in speaker, you
need to insert your external MIC or speaker cable into the round MIC or speaker

If you connected the modem to a computer, place the computer into terminal mode and
complete the configuration information required by the software. Refer to your software
manual to find out which commands to use.
Then use the following procedure to verify your modem connections:
1. Type AT and press the Enter key. The RD and TD LEDs flash on the modem front
panel. If your system is operating properly, your modem sends an OK response to your
computer screen and wait for your next command.
If the LEDs did not FLASH, or if you did not receive a response, make sure your computer
is sending commands to your modem at a speed of 300, 1200, 2400, 9600, 19200, 38400,
57600 or 115200bps. If this does not solve your problem, contact your computer dealer.
2. Use your communication software to prepare your computer to dial a call. Then type
ATD x phone number, where x is either T for Touch-Tone dialing or P for Pulse dialing
and phone number is the telephone number that your modem is using
For example, if your modem is connected to the telephone line 555-2121 and Touch-Tone
dialing is supported in your calling area, type ATDT 555 2121
3. Press the Enter key. You should receive a BUSY response and you should hear the
busy signal through the modem speaker because the modem is calling itself.
Your modem is now ready for operation. Refer to the manual that came with your
communication software to begin communication. If you will be communicating directly
with your modem, or if you want to find out more about the modem's operation, proceed to
use's manual.

Chapter 2 describes the format to use when typing modem commands. Chapter 2 also
describes the responses that your modem sends to your computer screen when you
execute, or try to execute, modem commands.
If you will be using a communication software program to make data calls, you will
probably not need to type commands, because your software program will handle these
tasks for you. Similarly, you will probably not see the responses because your software
program may intercept them.
However, if you perform data activities directly with your modem, you will find the format
for typing modem commands and modem response helpful.
2.1 Typing a command
Using commands, you can have your modem perform a variety of activities, such as
dialing or answering a data call or sending a fax. In order to send commands to your
modem, You must type a command line while your modem is in command mode.
2.2 To type a command line
1. Type AT. These characters must precede every command line. (except when you type
the A/ command, described on page 31)
2. Type the commands you want your modem to execute. A command line can contain
up to 40 characters.
3. Press the Enter key. The modem will then execute the commands on the command
line.
2.3 Correcting a typing mistake
If you make a mistake while typing a command, press the Backspace key to delete the
error. You can delete every command except AT.
2.4 Readability
To make a command line easy to read, you can insert spaces parentheses, hyphens, and
other punctuation in your command line. For example:
AT M3 DT 9, 1(818)555-1234
Your modem ignores spaces and punctuation when executing a command line, but these
characters apply to the 40 characters limit.

5634RCS User’s Manual
11
2.5 Typing more than 40 characters
If you want to type more than 40 characters on a command line, type a regular command
line (up to 40 characters long) and end it with a semicolon as the last character. When
you press Enter, your modem executes the commands and returns to command mode, so
you can type your next command line.
2.6 Omitting a parameter
Some commands require a numeric parameter such as 0,1, or 2. For example, the Q
command determines whether your modem sends a modem response after executing a
modem command line:
Q0 tells the modem to send responses.
Q1 tells the modem not to send response.
If you type ATQ and press the Enter key without typing a parameter of 0or 1after the Q,
it's like typing Q0 and the modem will send modem responses.
2.7 Repeating a command line
For your convenience, the last command line you execute remains stored in the modem's
memory until you type a new command line and press the Enter key. If you want to re-
execute the last command, type A/.
When you want to use the A/ command, you don't need to preface it with the AT
characters or end it by pressing the Enter key. Just type A/ to have your modem
automatically re execute the last command line.
The A/ command is particularly useful when you want your modem to re-execute a lengthy
command line or redial a number that was busy.
You can continue using A/ to automatically re-execute the last command line until you
type a new command line that begins with AT or reset your modem, or until your modem
loses power.
2.8 Modem responses
When you send a command to your modem, it sends a response to your computer. For
example, if you send a modem command to your modem, the modem should respond with
OK. You may never see these responses, however because certain communication
software will intercept them before they can be displayed on your computer screen.
This section describes the modem responses returned by the modem when you
communicate directly with the modem. If you will be using a communication software

5634RCS User’s Manual
12
program to make data calls, you may not see these responses because your software
program will probably intercept the responses.
Response sets
Modem responses can come from one of five response sets. These response sets are
designed X0, X1, X2, X3, and X4.
The response sets determine which modem responses are sent by the modem. They also
define certain dialing characteristics and how the modem handles dial tones and busy
signals, as described in the following sections.
2.9 Word or numeric responses
Modem responses can appear as words or numbers. Your modem is set up to return word
responses. Word responses are followed by a carriage return and line feed.
If your modem is operating under an application that handles character strings inefficiently
or cannot handle them at all, you can use the V0 command to switch to numeric modem
responses. Numeric responses are followed by a carriage return only.
If you do not want to receive modem responses at all, you can use Q1 command to
disable them. You may want to disable responses entirely if your modem is connected to a
printer and you do not want the modem responses printed.
2.9.1 X0 response set
The X0 response set consists of the first five responses in Table 2-1. with this response
set, you receive the CONNECT response for all connections, regardless of the speed at
which they're made.
When you send a Dial command line with this response set in effect, the modem will wait
two seconds after receiving your Dial command, then automatically dial the telephone
number whether or not a dial tone is present This is known as "blind dialing." You may
want to use blind dialing if you will be using the modem in an area that has an irregular or
weak dial tone that your modem cannot always detect.
2.9.2 X1 response set
The X1 response set consists of the all responses in Table 2-1, except NO DIALTONE,
BUSY and NO ANSWER. When you send a Dial command with this response set in effect,
your modem will blind dial call.
2.9.3 X2 response set
The X2 response set consists of all responses in Table 2-1, except BUSY and NO
ANSWER.

5634RCS User’s Manual
13
When you send a Dial command with this response set in effect, your modem will listen
for a dial tone before dialing. If it does not detect a dial tone within five seconds, it hangs
up and returns the NO DIALTONE response.
2.9.4 X3 response set
The X3 response set consists of all responses in Table 2-1, except NO DIALTONE.
When this response set is in effect and you send a Dial command to your modem, your
modem will blind dial the call. If the telephone number dialed is busy, your modem will
send the BUSY response.
2.9.5 X4 response set
The X4 response set is the factory-default response set. It consists of the all responses in
Table 2-1. This response set allows the modem to detect a dial tone and also a busy
signal.
2.10 Correction & compression responses
If your modem supports the MNP and V.42/V.42bis error-correction and data-compression
protocols, you can use the Wn command to enable the extended responses shown in
Table 2-1.
lThe Wcommand that enables negotiation progress responses is not the same
command as the Wdialing modifier used in dial command lines.
The default setting, W0, disables extended responses. With W0, all CONNECT responses
report the DTE speed.
To receive the CARRIER and PROTOCOL responses in Table 2-1, send the W1
command. When this command is in effect, the CONNECT response will show the DTE
speed.
If you want the CONNECT response to show the DCE speed rather than the DTE speed,
send W2 command. With this command, extended responses will be disabled.
Modems that support the MNP and V.42/V.42bis error-correction and data-compression
protocol can also use the \V1 command to append /ARQ to the end of all CONNECT
responses when your modem makes an error-correction data connection with a remote
modem.
If you do not want /ARQ appended to the end of CONNECT responses when an error-
correction data connection is made, send the \V0 command.

Your modem is preset so that you can begin transferring data files as soon as you install
the modem and load your communication software.
If you dialing and answering requirements do not match the modem's default configuration
profile, you can create your own profiles and store them safely in your modem's
nonvolatile memory. The profiles will be saved, even when you turn off your modem.
When you need to use a certain profile, send the appropriate command.
You can save two custom configuration profiles in your modem's nonvolatile memory. You
save profiles using &Wn command. The n can be the number 0 or 1, which corresponds
to the location in nonvolatile memory where you want the profile stored.
Using the &Wn command, you can store the following commands (refer to Chapter 5 for
description of these commands):
B1, T, E1, F0, L2, M1, Q0, V1, X4, Y0, &C0, &D0, &G0, &J0, &K3, &L0, &P0, \A3, \B2,
%C1, \N3 .........
You can also store the following register values (refer to Chapter 6 for a description of
these registers):
S0=0, S2=43, S6=2, S7=30, S8=2, S9=6, S10=14, S11=95, S12=50, S18=0, S25=5 ...
3.1 Storing a profile
The following example shows how you can store a profile. Assume that you want to save
the following commands in profile 0:
X1 E0 &C1 &D0 &M0 S0=3
To do so :
1. Type AT
2. Type the commands shown above
3. Type the &W0 command as the last command on the command line to save these
commands as user Profile 0.
4. Press the Enter key. This custom configuration profile is now saved under user Profile
0.
3.2 Recalling a profile
After you store a custom configuration profile, you can recall it using the AT&Yn
command. For example, to recall profile 0 :
Type AT&Y0

1. Press the Enter key. The next time you turn on or reset your modem, it will drive its
operating characteristics from Profile 0.
2. To recall Profile 1 instead of Profile 0, type AT&Y1 instead of AT&Y0.
3.3 Reset and recalling profile
If you prefer, you can use ATZn command to reset the modem and load a stored
configuration profile : For example, to reset your modem and recall Profile 0 :
1. Type ATZ0
2. Press the Enter key.
Returning to the default profile
1. To return to the factory default profile 0:
2. Type AT&F0
Press the Enter key. Your modem returns to basic asynchronous operation, which is the
profile in effect when you received your modem. The following table lists the modem's
default profile.
