This modem supports two-wire and/or four-wire leased lines. The four-wire leased line includes the dial
backup and automatic leased line restoration features. Please note that, because leased-line operation
consists of two client modems connected to each other, the maximum leased line data rate is 33.6K bps.
The MT5600BA-V.92 modem supports both two-wire and four-wire leased lines.
The MT5600BA modem supports a two-wire leased line.
The MT5600BL modem supports a four-wire leased line.
The MultiModemII offers interactive automatic dialing. You can store four command lines or telephone
numbers of up to 30 characters each in the modem’s nonvolatile memory. The modem pulse- or tonedials, and recognizes dial tones and busy signals for reliable call-progress detection. It can also detect
AT&T calling card tones. It is FCC-registered for connection to telephone networks without notification to
the telephone company.
The MultiModemII front panel includes a liquid crystal display and four buttons, which together can be
used to either display the current connection status of the modem or to configure the modem. The
MultiModemII also can be configured through standard AT commands.

PowerOn Test
Test the modem by turning it on (a power switch is located on the front panel). When you apply
power, the modem performs a diagnostic self-test, indicated by the TM indicator lighting for a few
seconds, after which the LCD should light. If this does not happen, check that the power switch is
on, the power transformer is solidly connected, and the AC outlet is live. If these measures do not
work, see the “Troubleshooting” chapter.

If you are comfortable using AT commands, you can use them to configure your modem. You
must enter these commands in your communication program's terminal window. You can use a
communication program such as PhoneTools. See Step 4 below.
How to Change the Country/Region Code
1. View the list of available country/region codes to find your country/region code by
executing the command AT +GCI? <CR>
Note: A list of country/region codes is also available on the Multi-Tech Web site at:
http://www.multitech.com/PRODUCTS/Categories/Modems/global/
configuration.asp#chart
2. Set and save the code by executing the following command:
AT+GCI=nn <CR> (where nn is the country/region code).
3. OK displays.
4. The code then displays.
How to Verify the Code
1. Type AT+GCI?<CR>
or you can use this command:
ATI5<CR>
Example
1. Type AT+GCI=B5<CR> to set B5 as your country/region code.
2. Type AT+GCI?<CR> or ATI5<CR> to verify that B5 was set.
B5 indicates the configuration is set for any B5 country such as Canada and the United
States.

Note: PhoneTools may or may not be included on the MultiModemII CD according to your company's
preference.
Data communications software gives you access to commands that govern how the modem operates;
that is, how the modem handles incoming and outgoing data streams, etc.
MultiTech includes a data communications software package (PhoneTools) on the product CD shipped
with your modem. In general, the modem will work with most data communications software packages.
1. Insert the MultiModemII CD into your CD-ROM drive. Allow Autorun to bring up the introductory
screen.
2. Click on the PhoneTools icon and choose the appropriate language.
3. Follow the PhoneTools installation wizard. No input is needed. You may choose to view the
“Readme” file and whether or not to run PhoneTools immediately.
Windows NT/2000/XP Note: During installation, an advisory screen may appear saying “FAX
capture driver installation” - this may cause a delay in the installation. This is normal. The
installation process has not failed or stalled. Simply wait a few moments until this screen
disappears.
4. After installation, you can launch PhoneTools either from a desktop icon or from the Start |
Programs menu. Typically, it’s not necessary to reboot before using PhoneTools.

Your modem normally is configured through Windows or through the communication program you are
using. The default settings work best for most purposes. See “Step 4: Install PhoneTools” in Chapter 2 for
help in setting up your communication program.
You also can configure your modem either through the front panel or by sending AT commands to the
modem. The AT commands can be found in the AT Reference Guide on the CD shipped with this
modem.

LED Indicators
The MT5600BA-V.92 has six LED indicators on the front panel that indicate status and activity:
Receive Data. The RD indicator flashes when the modem is receiving data.
Transmit Data. The TD indicator flashes when the modem is transmitting data.
Carrier Detect. The CD indicator lights when the modem detects a valid carrier signal from
another modem. It is on when the modem is communicating with the other modem, and off when
the link is broken.
Off-Hook. The OH indicator lights when the modem is off-hook, which occurs when the
modem is dialing, online, or answering a call. The LED flashes when the modem pulse-dials.
Terminal Ready. The TR indicator lights when a communication program is using the
modem. It means the modem is ready for an outgoing or incoming call. It goes off when the
communication program disconnects the serial port. When it goes off, a connected modem will
disconnect.
Test Mode. The TM indicator lights when the modem is in test mode.

This chapter describes how to use the MultiModemII modem on a leased line.
A leased line is a private, permanent, telephone connection between two points. Unlike normal dialup
connections, a leased line is always active. The modems automatically connect when they are attached
to the line and are turned on. Because a leased line is always active, one of the two modems on the line
must be configured as the originate modem and the other as the answer modem; however, it does not
matter which is which.
In the event of an interruption, leased line modems automatically reconnect when the data line or power
is restored. The modem also supports dial backup, which enables the modem to automatically switch to a
dial-up connection if the leased line goes down.
The modem supports both two-wire and four-wire leased-line operation.

For four-wire leased line operation, the MT5600BA-V.92 modem has a dial backup capability, in which
the modem is connected to a standard dial-up line as well as to the leased line. If the leased line fails, the
originate modem automatically dials and connects to the answer modem through the standard telephone
network. While it is in dial backup mode, the modem periodically checks the leased line to see if it is
operational. If the line is operational, the modem then attempts to restore the leased line. If the modem
detects that it is not connected to the standard telephone network when the leased line fails, it
immediately switches to leased line restoral.
The dial-back timer, register S17, determines how long the modem waits after a leased line failure before
it attempts a dial backup connection. The S17 default setting is one minute. During that minute, the
originate modem tries to establish the leased line link. If the leased line is established during that time,
the S17 timer is cleared and everything is back to normal. If the timer expires, the modem attempts a dial
backup connection. The purpose of the timer for the answer modem is to determine when it can accept a
dial-up call. Dial-back starts only when both timers have expired and the leased line is still down.
The restore timer, register S15, determines how frequently restoral attempts occur when the modems are
in dial backup mode. S15 can be set from 10 to 255 minutes in one minute increments. A value of 0
disables dial backup. The default value is 30 minutes.
Note: Register S15 must be set identically on the local and remote modems.
The dial backup number must be set from the front panel of the modem.

The following steps are valid regardless of whether the connection is established by the local or the
remote MultiModemII modem.
1.
Establish a data connection with a remote MT5600BA-V.92 modem.
2.
Send three asterisks to initiate remote configuration. The remote modem responds:
Online Remote Access
Remote password:
3.
Type the remote configuration password, and then press ENTER. The default is “MULTITECH.” It is
not case-sensitive.
•
If the password is incorrect, the word CONNECT appears, and the local modem is returned to
online mode.
•
If the password is correct, an >AT_ command prompt appears.
4.
Type AT commands to configure the remote modem. It is not necessary to precede the commands
with “AT.”
5.
When you have finished configuring the remote modem, type *E and press ENTER to exit remote
configuration mode and return to online data mode. You can now break the connection in the normal
way.
Note: The dialing command is not allowed in remote configuration mode.

To improve security, you can change a remote modem’s remote configuration escape character. The
remote configuration escape character is stored in register S13. The factory default is 42, which is the
ASCII code for the asterisk character (*). Setting S13 to 0 (zero) disables remote configuration entirely—
but if you do this remotely, you won’t be able to change it back remotely!
1. Establish a remote configuration link with the remote modem as described in
“Basic Procedure.”
2. Type ATS13=n, where n is the ASCII code for the new remote configuration

This chapter describes how to use callback security with your modem.
Callback security protects your network from unauthorized access and helps control long distance costs.
When callback security is enabled, all callers are requested to enter a password. If the password is
invalid, the caller can try twice more before the modem hangs up. If the password is valid, the modem
hangs up and returns the call by dialing the phone number associated with the password.
It is possible to implement password protection without callback by storing a hyphen (-) before the
callback phone number. The caller must then append a hyphen to his password to establish the direct
connection.
The modem can store up to 30 callback phone numbers and 30 callback passwords. Phone numbers can
be up to 30 characters long and can contain the pause (,) and wait (W) characters in addition to the digits
and characters normally found on a touch-tone keypad. Passwords can be up to 10 characters long.
Callback phone numbers are associated with callback passwords by being assigned to the same callback
memory location. For example, if you assign the password “APRICOT” to memory location 16 and, in a
separate operation, also assign phone number 6127853000 to memory location 16, the modem calls
phone number 6127853000 when it receives the password “APRICOT.”
Because there is no way to examine the passwords and phone numbers stored in the modem, it is
important to write them down as you enter them. A form that you can print out for this purpose is provided
on the last page of this chapter.

In the terminal window, type one of the following commands:
•
To turn on callback security, type AT#DB1 and press ENTER. With remote callback security
turned on, each caller is asked to enter a password, then is disconnected and called back by
the modem. Also, dialing number locations 0–3, for use with the DS=y dialing command, are
replaced by callback dialing number locations 1–30.
•
To turn off callback security, type AT#DB0 and press ENTER. Callers no longer need a password
to connect to the modem, the modem is unable to call them back, and stored dialing number
locations 0–3 become available.

Use the following procedure to call a modem that has callback security enabled.
Note: Autoanswer must be enabled on the calling modem (S0=1 or S0=2).
1. Using a data communication program such as HyperTerminal, dial the number of
the callback modem.
2. When the connection is established, the callback modem responds with a
request for a password.
3. Type the password for your modem, and then press ENTER. You have three
attempts to enter a valid password or be disconnected.
4. If the password is valid, the callback modem disconnects. Then, after a short
delay, it calls the number associated with the password and establishes a
working connection.
Note: If you are calling a direct connect number, you must append a hyphen (-) to
the password. If the corresponding phone number has - as its first character, you will
be able to go directly online with the callback modem. If the corresponding phone
number has no - character, you will be prompted for a different password.

Your modem was thoroughly tested at the factory before it was shipped. If you are unable to make a
successful connection, or if you experience data loss or garbled characters during your connection, it is
possible that the modem is defective. However, it is more likely that the source of your problem lies
elsewhere. The following symptoms are typical of problems you might encounter:
•
None of the LEDs light when the modem is on.
•
The modem does not respond to commands.
•
The modem cannot connect when dialing.
•
The modem disconnects while online.
•
The modem cannot connect when answering.
•
File transfer is slower than it should be.
•
Data is being lost.
•
There are garbage characters on the monitor.
•
The modem doesn’t work with Caller ID.
•
Fax and data software can’t run at the same time.
If you experience problems, please check the following possibilities before calling Technical Support (see

When you turn on the modem, the LED indicators on the front panel should flash briefly as the modem
runs a self-test, and the liquid crystal display (LCD) should light. If the LEDs and LCD remain off, the
modem is probably not receiving power.
•
Make sure the modem’s power switch is on, especially if you normally turn the modem on by turning
on a power strip.
•
If the modem is plugged into a power strip, make sure the power strip is plugged in and its power
switch is on.
•
Make sure the transformer module is firmly connected to the modem and to the wall outlet or power
strip.
•
If the power strip is on and the modem switch is on, try moving the transformer module to another
outlet on the power strip.
•
Test that the outlet is live by plugging another device, such as a lamp, into it.
•
The modem or transformer module may be defective. If you have another Multi-Tech modem, try
swapping modems. If the problem goes away, the first modem or transformer module may be
defective. Call Technical Support for assistance.
CAUTION: Do not under any circumstances replace the transformer module with one designed for
another product; doing so can damage the modem and void your warranty.

Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”)
•
Make sure you are issuing the modem commands from data communication software, either
manually in terminal mode or automatically by configuring the software. (You cannot send
commands to the modem from the DOS prompt.)
•
Make sure you are in terminal mode in your data communication program, then type AT and press
ENTER. If you get an OK response from your modem, your connections are good and the problem
likely is in the connection setup in your communication software.
•
Try resetting your modem by turning it off and on. If you are using DOS or Windows 3.1
communication software, make sure the initialization string includes &F as the first command, to
cancel any “leftover’ command that could affect the modem’s operation.
•
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 the modem is connected to.
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.
Windows 3.1x: To look for address or IRQ conflicts, in Program Manager select File | Run, type
MSD, and press ENTER. Then select Mouse, COM Ports, and IRQ Status, and note the addresses
and IRQs that are in use. If you find an IRQ conflict, note which IRQs are not being used, then
change one of the conflicting devices to use one of the unused IRQs. If you find an address conflict,
change the address of one of the conflicting devices.
To change a port address or IRQ in Windows 3.1x, double-click the Control Panel icon, then the
Ports icon. Click on the port you want to change, click Settings, click Advanced, and select the
new port address and/or interrupt. If you wish to use COM3 or COM4, note that COM3 shares an
IRQ with COM1, as does COM4 with COM2, so you should change their IRQs to unused ones, if
possible.

Windows 9x: Right-click on My Computer, select Properties from the menu, click on the Device
Manager tab, double-click on Ports, then double-click on the communication port your modem is
connected to. In the port’s Properties sheet, click on the Resources tab to see the port’s input/
output range and interrupt request. If another device is using the same address range or IRQ, it
appears in the Conflicting Device List. Uncheck Use automatic settings to change the port’s
settings so they do not conflict with the other device, or select the port the conflicting device is on
and change it instead. If you need to open your computer to change switches or jumpers on the
conflicting device; refer to the device’s documentation.
Windows NT 4.0: To look for address or IRQ conflicts, click Start, Programs, Administrative Tools
(Common), and Windows NT Diagnostics. In the Windows NT Diagnostics dialog box, click the
Resources tab to see which input/output ranges and interrupt requests are in use. If you need to
open your computer to change switches or jumpers on the conflicting device; refer to the device’s
documentation.
•
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 MultiTech modem, try swapping modems. If the problem goes away, call Technical Support for
assistance (see Appendix D).

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.
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 ENTER. 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 (note,
however, that X3 is not allowed in some countries, such as France and Spain).

If the modem reports BUSY, the other number might be busy, in which case you should try again
later, or it might indicate that you have failed to add a 9, prefix to the phone number if you must dial
9 for an outside line.
If you must dial 9 to get an outside line, the easiest way to dial it automatically is to include it in the
modem’s dial prefix, e.g., ATDT9,. Note the comma, which inserts a pause before the number is
dialed. By inserting 9, into the dial prefix, you do not have to include it in each directory entry.
To change the dial prefix in Windows 95 HyperTerminal, select Connect from the Call menu, click
Dialing Properties, and type 9 in the local and long distance boxes in How I dial from this
location.
•
If the modem reports NO ANSWER, the other system has failed to go off-hook, or you might have
dialed a wrong number. Check the number.
•
If the modem reports NO CARRIER, the phone was answered at the other end, but no connection
was made. You might have dialed a wrong number, and a person answered instead of a computer,
or you might have dialed the correct number but the other computer or software was turned off or
faulty. Check the number and try again, or try calling another system to make sure your modem is
working. Also, try calling the number on your telephone. If you hear harsh sounds, then another
modem is answering the call, and the modems might be having problems negotiating because of
modem incompatibilities or line noise. Try connecting at a lower speed.

If you have Call Waiting on the same phone line as your modem, it can interrupt your connection
when someone tries to call you. If you have Call Waiting, disable it before each call. In most
telephone areas in North America, you can disable Call Waiting by preceding the telephone number
with *70 (check with your local telephone company).
You can automatically disable Call Waiting by including the disabling code in the modem’s dial
prefix (e.g., ATDT*70,—note the comma, which inserts a pause before the number is dialed). To
change the dial prefix in Windows Terminal, select Settings | Modem Commands. To change it in
HyperTerminal, select Connect from the Call menu, click Dialing Properties, check This location
has Call Waiting, and select the correct code for your phone service.
•
If you have extension phones on the same line as your modem, you or someone else can interrupt
the connection by picking up another phone. If this is a frequent problem, disconnect the extension
phones before using the modem, or install another phone line especially for the modem.
•
Check for loose connections between the modem and the computer, the telephone jack, and AC
power.
•
You might have had a poor connection because of line conditions or the problem might have
originated on the other end of the line. Try again.

The default DTR Control command (&D2) inhibits autoanswer. To enable autoanswer, change DTR
Control to &D0, and make sure &Q0, &Q1, &Q5, or &Q6 is also set. For more information, see the
&D command in the AT Command Reference Guide on the CD shipped with your modem. For
information on changing the modem’s default configuration, see “Step 3: Install and Configure Your
Software” in Chapter 2.

Autoanswer might be disabled. Turn on autoanswer in your datacomm program or send the
command ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.

•
You might have an older UART. For best throughput, install a 16550AFN UART or a Multi-Tech ISI
serial port card.
•
If you are running under Windows 3.1 and have a 16550AFN UART, you must replace the
Windows serial driver, COMM.DRV, to take full advantage of the UART’s speed.
•
If you are using a slow transfer protocol, such as Xmodem, try Zmodem or Ymodem/G instead.
•
Is your line noisy? If there is static on your line, the modem has to resend many blocks of data to
insure accuracy. You must have a clean line for maximum speed.
•
Are you downloading a compressed file with MNP 5 hardware compression enabled? Since
hardware data compression cannot compress a file already compressed by an archiving program, the
transfer can be marginally slower with data compression enabled than with it disabled.
•
Does your Internet service provider (ISP) use the same 56K protocol as your modem? The default
setting of your modem is to connect using either the 56K or the V.90 protocol, depending on which
one the ISP modem is using. If your ISP uses the X2 protocol, the maximum speed you will be able
to connect at is 33,600 bps. Check with your ISP to see which protocols it supports, and check the
Multi-Tech Web site for the latest developments in V.92.

Try entering the &V1 command to display information about the last connection, making a screen

•
If you are using data compression and a high speed serial port, set the serial port baud rate to four
times the data rate.
•
Your UART might not be reliable at serial port speeds over 9600 bps or 19,200 bps. Turn off data
compression, reset your serial port speed to a lower rate, or replace your serial port with a faster
one.
•
Make sure the flow control method you selected in software matches the method selected in the
modem. If you are using the modem with a Macintosh, you might have the wrong cable for
hardware flow control.
•
Try entering the &V1 command to display information about the last connection, making a screen

Your computer and the remote computer might be set to different word lengths, stop bits, or
parities. If you have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your
communication software.
•
You might be experiencing line noise. Enable error correction, if it is disabled, or hang up and call
again; you might get a better connection the second time.
•
At speeds above 2400 bps, the remote modem might not use the same transmission or error
correction standards as your modem. Try connecting at a slower speed or disabling error
correction. (With no error correction, however, line noise can cause garbage characters.)

Caller ID information is transmitted between the first and second rings, so if autoanswer is
turned off (S0=0) or if the modem is set to answer after only one ring (S0=1), the modem will not

4. This device is equipped with pulse dialing, while the Telecom standard is DTMF tone dialing. There is
no guarantee that Telecom lines will always continue to support pulse dialing.
Use of pulse dialing, when this equipment is connected to the same line as other equipment, may
give rise to ‘bell tinkle’ or noise and may also cause a false answer condition. Should such problems
occur, the user should not contact the Telecom Faults Service.
The preferred method of dialing is to use DTMF tones, as this is faster than pulse (decadic) dialing
and is readily available on almost all New Zealand telephone exchanges.
5. Warning Notice: No ‘111’ or other calls can be made from this device during a mains power failure.
6. This equipment may not provide for the effective hand-over of a call to another device connected to
the same line.
7. Some parameters required for compliance with Telecom’s Telepermit requirements are dependent on
the equipment (PC) associated with this device. The associated equipment shall be set to operate
within the following limits for compliance with Telecom’s Specifications:
For repeat calls to the same number:
•
There shall be no more than 10 call attempts to the same number within any 30-minute period for
any single manual call initiation, and
•
The equipment shall go on-hook for a period of not less than 30 seconds between the end of one
attempt and the beginning of the next attempt.
For automatic calls to different numbers:
•
The equipment shall be set to ensure that automatic calls to different numbers are spaced such
that there is no less than 5 seconds between the end of one call attempt and the beginning of
another.
For automatically answered incoming calls:

Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory.
Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However, it can
be changed by either the manufacturer or the user as bugs are fixed or new features are added.
Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few minutes
by using the following procedures.

The upgrade procedure consists of the following steps, which are described in greater detail in the
following sections.
1.
Identify the model number and firmware version of your modem.
2.
Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has
the current firmware, there is no need to update it.
3.
Download the upgrade file for your modem.
4.
Extract the firmware .HEX file and the appropriate flash upgrade program from the file you
downloaded.
5.
Document and clear your stored parameters.
6.

You must know the model number and firmware version of your Multi-Tech modem to know whether or not
you should update it.
1.
Run your favorite terminal program. If you are using Windows, you can use HyperTerminal.
2.
In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on your
screen, be sure to type it completely, and then press Enter. If the modem does not respond with OK,
repeat the AT&F command.
3.
Now type ATI3, press Enter and record your results. The firmware version should appear first in the
response, which should look similar to the following:

2.
Scroll down the table to your modem model number.
3.
Look at the firmware version number for your modem.
4.
If the firmware version number matches the firmware version number found in “Step 1: Identify the
Modem Firmware,” your modem has the current firmware version, and does not need to be updated.
5.
If the firmware version number is greater than the firmware version number found in “Step 1: Identify
the Modem Firmware,” your modem has an older firmware version. Continue with “Step 3: Download
the Upgrade File.”
Warning: The first digit of the new firmware must match the first digit of the old firmware, or the modem
may not work properly; e.g., if your current firmware version is 4.16, replace it only with 4.xx firmware, not

Internet. Linux can use different programs and desktops depending on who made the Linux operating
system and what version it is. The following procedures use the most commonly installed components of
Red Hat 6.2. More information can be found in your Linux OS owner’s manual.
Using the Terminal Program Minicom to Verify Operation
1.
At the command prompt, type minicom –s and press Enter.
2.
Select Serial port setup and press Enter.
3.
From Serial port setup, use the A key to access Serial Device, and then press Enter.
4.
Press ESC.
5.
You are now in the Minicom terminal. Type AT and press Enter. The screen should display OK to
verify the operation. Alternately, dial a phone number to verify line operation

Appendix D - Installing a Modem Under Linux
Using the Modem to Call the Internet
Linux allows different graphic user interfaces (GUI). In the following steps, we’ll use the Gnome Desktop
GUI and assume that the Internet Service Provider (ISP) you are calling assigns you the Domain Name
Service (DNS) and Internet Protocol (IP) addresses. For more information on DNS or IP, see the Linux
OS owner’s manual or contact your ISP.
1.
On the Task Bar at the bottom of the screen, select the Gnome Footprint.
2.
Select Internet from the menu.
3.
Select Dialup Configuration Tool.
4.
Select Add, and then click Next.
5.
Enter the connection name and phone number, and then click Next.
6.
Enter your user name and password, and then click Next.
7.
Select Normal ISP if your ISP is not listed, and then click Next.
8.
Click Finish.
Calling the ISP
1.
On the Task Bar at the bottom of the screen, select the Gnome Footprint.
2.
Select Internet from the menu.
3.
Select RH PPP Dialer.
4.
Select the connection name you entered in step 5 of the previous section.
5.
Click OK.
Answering Calls
To use the system for answering calls, Linux requires other programs to be installed, such as Mgetty,
Mgetty+Sendfax, and others, depending on your requirements. Each vendor of Linux has more than
adequate information on installing these programs.

TD
2
Transmitted Data The DTE uses the TD line to send
data to the modem for transmission over the telephone
line or to transmit commands to the modem.
RD
3
Received Data The modem uses the RD line to send
data received from the telephone line to the DTE and to
send modem responses to the DTE.
RTS
4
Request to Send The RTS signal is used for hardware
flow control.
CTS
5
Clear To Send CTS is controlled by the modem to
indicate whether or not the modem is ready to transmit
data. CTS high indicates to the DTE that signals
presented on TD will be transmitted to the telephone
line. CTS low indicates to the DTE that it should not
transfer data across the interface on TD.
DSR
6
Out
Data Set Ready DSR indicates modem status to the
DTE. DSR low indicates that the DTE is to disregard all
signals appearing on the interchange circuits except
Ring Indicator (RI). It reflects the status of the local data
set, and does not indicate an actual link with any remote
data equipment.
GND

GND
Ground.
CFLO
8
CD
Carrier Detect The modem uses the CD line to signal
to the DTE that a carrier has been detected.
+12V
