About Windows 95 Prompts

During setup, Windows 95 may prompt for an Installation Disk or the Windows CD several times. Be sure that the path or device you supply to this prompt is correct. Here are some guidelines:

■

If Windows 95 prompts for a disk from the manufacturer, put the LAN+Modem card

Windows 95/98 Installation Disk in the ﬂoppy drive. On most systems, this

will be drive A, so the path in the dialog box should point to A:\. If Windows 95 prompts for the Windows CD, put the Windows 95 CD in your

■

CD-ROM drive. Often, this will be drive D. If so, the path in the dialog box should point to D:\WIN95.

■

Some computers are delivered with Windows 95 installed, but no CD is supplied. If this is the case with your computer, you must supply the path where the Windows 95 software resides. Check your owner’s manual for details. Often, this will be a subdirectory of your Windows folder. A common path for these driver ﬁles is C:\WINDOWS\OPTIONS\CABS, so you would supply this path in the dialog box.

Sometimes earlier installations or interrupted installation attempts leave problems that affect card operation. Possible problems include:

■ One or both of the card functions not working.

■ Windows 95 not detecting the card.

■ The system issuing a warning tone at startup.

If you are having any of these problems, remove the LAN+Modem card and software using the procedures below, then reinstall the card.

Removing the Card Check your computer manual for information on removing cards. Store the car d in

its original or similar packaging.

CAUTION: Exit any communications or networking applications before removing the card.

Using the Device Manager to remove the LAN portion of the card fr om the Device Manager will uninstall the card, software and documentation.

Be sure to remove both the LAN interface and the modem.

Troubleshooting

Symptom Solution

Basic Troubleshooting, applicable for all problem situations.

System shows a valid COM-Port setting for the modem, but your application does not recognize it.

The LAN device is not functional. LED on the connector is off or mismatches the real network speed.

After you remove the card from the system and then inserted back – Windows runs installation process again.

Inspect all cables and connections. Check whether your card if fully inserted into the slot. Verify whether you have the latest BIOS for your system. If not, check the Web

site for your computer, download the newest BIOS version, and follow the upgrade instructions.

Check for multiple installations of the card. Check whether your system’s PC Card CardBus Controller is installed and

running properly: go to Control Panel/System/Device Manager/PCMCIA Card and verify that the controller is present and shows no errors.

Check the Control Panel/PC Card application to confirm that your card is recognized by the system.

In the Control Panel/Network application, make sure that you have appropriate clients and protocols installed.

Use the 3Com Modem Setting application in the control panel to change the COM port assignment. The default is COM5. Use a lower number if you are have older software that does not recognize COM ports higher than 4.

Use Control Panel – Device Manager to inspect the status of your LAN card. If you see a red X, enable the card and set the Properties. If yo see a yellow exclamation mark, click on the icon to see what the conflict is.

Verify that there are adequate system resources. Try to free system resources (e.g. disable the infrared port), then remove and reinstall the card.

This is normal behavior for Windows with PCI and CardBus cards installed. Windows 95 can install one instance of the card for every slot presented in the system. You will have two instances of the card under the Network and Modem applications in Control Panel. After the second instance is installed – the hot swap from one slot to another will be smooth. Be sure to check your settings under Dial-up Networking and Hyperterminal to ensure that your preferred settings apply to the correct instance of the card.

The card does not work in your system with Windows 95 or Windows 95a

Losing network connection after disconnecting or changing the media speed when using NetWare servers and IPX/SPX protocol

After reboot in Dell Latitude CP the card does not come up.

Earlier versions of Windows (Windows 95 and Windows 95a) are not supported. Upgrade your system to Windows 95b (OSR2) or Windows 98.

To determine your version of Windows 95, open the Control Panel, select System, and look at System information under the General tab. If your release is identified as version 4.00.950 B, you are using OSR2.

This happens when the frame type is selected automatically. A temporary solution is to reboot after disconnecting and reconnecting the cable in NetWare networks. The permanent solution is to use specific frame types such as 802.2 or 802.3.

A temporary solution is to remove the card from the slot and then insert it again. For a permanent solution, use the original Dell Windows 95 installation CD or obtain QFE 515, 567 and 599 from Microsoft or Dell. Copy these files into the Windows/System folder.

In the Control Panel/Network application, make sure that you have appropriate Clients and Protocols installed.

Use the 3Com Modem Setting application in the control panel to change the COM port assignment. The default is COM5. Change the COM port to a lower number if you are using older software that does not recognize COM ports higher than 4.

Use Control Panel – Device Manager to inspect the status of your LAN card. If it comes with a red cross – enable the card checking the appropriate box

under Properties If it comes up with a yellow exclamation mark, click on the icon to see what the

conflict is. Verify that there are adequate system resources. Try to free system resources (e.g. disable the infrared port), then remove and reinstall the card.

After you remove the card from the system and then inserted back – Windows runs installation process again

Losing network connection after disconnecting or changing the media speed when using NetWare servers and IPX/SPX protocol

After a fresh installation of Windows 98 with the card already installed, the system detects the card interface as PCI device.

This is normal behavior for Windows with PCI and CardBus cards installed. Windows 98 can install one instance of the card for every slot presented in the system. (If you proceed with this installation, you will need your LAN+Modem card Windows 95/98 Installation disk.) You will have two instances of the card under the Network and Modem applications in Control Panel. After the second instance is installed – the hot swap from one slot to another will be smooth. Be sure to check your settings under Dial-up Networking and Hyperterminal to ensure that your preferred settings apply to the correct instance of the card.

This happens when the frame type is selected automatically. A temporary solution is to reboot the system after disconnecting /reconnecting the cable in NetWare networks. The permanent solution is to use specific frame types such as 802.2 or 802.3.

During a fresh installation of Windows 98 with the card installed in the slot, the system detects the card as PCI device and does not ask for the driver disk. This happens only when you reply “No” when asked whether the card is used for Windows installation.

Check Control Panel/System/Device Manager. Remove the"PCI Device" entry and reboot the system. Windows 98 will detect the card and prompt for the Windows 95/98 Installation disk.

WINDOWS NT

NOTE: If you are reinstalling the card, make sure you have completed the

procedures for “Uninstalling the Card” on page 23. For Windows NT 4.0 installation, you must have Service Pack 3 (or later) installed on your computer. After installation, reinstall Service Pack 3 to update NT network ﬁles and eliminate error messages in the Event Viewer. Contact your Network Administrator or Microsoft if you do not have Service Pack 3.

Installing the Network Interface

This procedure assumes that you are installing the LAN+Modem card on a system that does not have NT networking installed. If networking is installed, some steps will not apply and some of the prompts will be slightly differ ent. Refer to your MIS department for instructions.

Before installing the network interface, insert the LAN+Modem card and connect to the network as described in “Installing and Connecting the Card” on page 1. Also, obtain the following information from your MIS department:

■ Your computer name and workgroup or domain name. This is required for

Windows NT networking.

■ Your user name and password. This is required for your network account.

To install the network interface:

1 In the Control Panel, double-click Network. 2 When the system prompts: ”Windows NT Networking is not installed. Do you

want to install it now?”, click Yes. This opens the Network Setup Wizard.

USING THE MODEM

Hints for Good Connections

Use the following information when you set up your communications software to help your modem connect at the highest possible speed:

■ If you have call waiting, disable it. Call waiting generates a tone on the line

that causes results similar to static. It also causes your modem to disconnect or report NO CARRIER if a call waiting signal comes when your modem is connected to another modem. Call waiting is usually disabled by using *70 in your dial string before the phone number, for example:

ATDT*70 151217288528

Contact your phone company if you need more information.

■ Telephone lines with static or noise slow down transmission and require error

correction. If your phone line has a problem with noise, contact your telephone company to see if they can ﬁx the problem.

■ Don’t use a splitter on your telephone line. A single connection from wall to

modem produces the highest transfer speed.

■ If the modems do not connect during the handshake, try disabling error

correction (use the AT command AT/N0). You can also try disabling data compression (AT/C0).

Software Settings Communications software setup requires information about the modem to make

a call or send a fax using the modem. Enter the following settings with the modem software you are using:

Setup for Communications Applications

■ Select the highest transmission speed or baud rate listed, up to 115,200 bps

■ Select fax Class 1

■ Select NONE for parity

■ Select a word length of 8

■ Set the stop bits to 1

■ Select either Hayes-compatible, Generic 28.8, or Generic 33.6 modem.

Virtually all data or fax communications software packages will work if set up correctly for your modem. Read and follow the software installation and setup instructions supplied with your communications application.

If the LAN+Modem card is listed in your communications software, the correct initialization strings will be used. If the correct modem does not appear on the list, use the generic 28.8 or 33.6 modem setting.

26 CHAPTER 5: USING THE MODEM

For most applications, you can use the factory-default setting for the modem initialization string. To reset your modem to the factory defaults, use the AT command string AT&F. For more information, see “S Registers” on page 32.

Making a Call with HyperTerminal

HyperTerminal is the resident telecommunication application supplied with Windows 95 and Windows NT 4.0. This section shows you how to place a call using HyperTerminal.

1 Close any open applications you are not using. Be especially sure to close any

communication programs.

2 Click on Start/Programs/Accessories/HyperTerminal.

3 Double-click the HyperTerminal icon to open the New Connection window.

In Windows 95 and Windows NT, you can ﬁnd the Hyperterminal icon in Start/Programs/Accessories/Hyperterminal.

In Windows 98, look in Start/Programs/Accessories/Communications.

4 In the Connection Description dialog box, type a text description, such as an

easy-to-remember name, for the connection and click OK.

5 In the Phone Number dialog box, type in the area code and phone number, for

example 151217288528 (“1” followed by the area code and number of the Dell BBS).

6 In the Connect Using menu, be sure that you have selected the 3Com 10/100 +

56K PC Card. If it does not appear, your modem is not installed correctly.

7 Click OK.

8 When the Connect dialog box appears, choose the location and the dialing

properties (for example, dial a 9 to access an outside line, dial a 1 before long distance, wait for a dial tone, and so forth) you require to make the call fr om your site.

Making Calls from a Hotel or Business PBX

9 Click Dial to initiate the call and make the connection.

You may hear a brief handshaking as the modem tries to establish a connection.

Normally, your LAN+Modem card waits for a dial tone before dialing. In some cases, however, a modem cannot detect a dial tone even when voice calls can be completed. This problem can occur when:

■ Dialing into a standard telephone network using nonstandard dial tone

conventions

■ Placing a call from a country outside of the United States, where a dif ferent dial

tone is used

■ Dialing through a business or hotel PBX or a voice-mail system that indicates

new mail with a unique dial tone (travelers often ﬁnd that hotel PBXs have unique dial tones)

■ Using telephones (such as cellular telephones) that require you to press a

button before the dial tone can be heard

Try the following suggestions for restoring the standard dial tone:

Additional Modem Features 27

■ Clear your voice mail.

■ Press the dial or line button on your telephone.

■ Access an outside line before dialing.

■ Reconﬁgure the dialing options for your communications package. Most

packages have a Wait for Dial Tone Before Dialing option that you can enable or disable if your modem is having trouble detecting a dial tone. You must disable this option to permit blind dialing.

Additional Modem Features

■ Redialing

■ Dialing Stored Numbers

■ Call Progress Detection

■ Fax Support

Redialing Your modem stor es each dialed number until another number is dialed. When you

ATDL, the modem redials the last number dialed.

enter

Dialing Stored Numbers The modem can store up to four telephone numbers. For example, suppose you

frequently call the number 555-5555. If this is the ﬁrst number you want to store, enter

AT&Z1=5555555 and ATDS1 to dial it. If it is the fourth number you want to

store, you would type

AT&Z4=5555555 to store it and ATDS4 to dial it.

Call Progress Detection An optional set of result codes lets you know when:

■ The telephone number you have dialed is busy

■ The line has been picked up, but a modem is not answering the call

■ There is no dial tone on the telephone line

■ A call is coming in

These result codes, and the commands that enable or disable these result codes are controlled by the ATXn command.

Fax Support To send or receive faxes using the modem, you must have a facsimile software

package, such as Microsoft Fax, provided with your notebook computer. In your fax software, select error-correcting mode (ECM) to provide more reliable fax connectivity. Your modem supports Class 1 and Class 2.0 faxing; for best results and compatibility, we recommend using Class 1 as your fax class.

NOTE: The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other electronic device to send any message via a telephone fax machine unless such message clearly contains in a margin at the top or bottom of each transmitted page or on the ﬁrst page of the transmission, the date and time it is sent and an identiﬁcation of the business or other entity, or other individual sending the message and the telephone number of the sending machine or such business, other entity, or individual.

28 CHAPTER 5: USING THE MODEM

Attaching this information to faxes is known as fax branding. Refer to your fax communication software documentation for details on how to comply with the fax-branding requirement.

AT Commands AT commands are set at the factory (factory settings are called defaults) to

perform speciﬁc modem functions in preselected ways. They can be used to display call status or send and receive data with communications software such as HyperTerminal.

Entering AT Commands

A T commands are instructions typed at the command line of any communications application. A communications application is in command mode when the application is started but the modem has not yet dialed. When your application is in command mode, the AT commands you type are sent directly to the modem.

The most common way to enter AT commands is from terminal mode in your communications software. The basic rules for entering AT commands are:

■ All AT command lines must begin with the preﬁx AT.

■ Spaces between command characters (and option characters) are ignored.

■ Command line parameters cannot exceed 255 characters.

■ Use a carriage return [Enter] to enter a command line. Commands take effect

as soon as they are received.

■ Type commands in either upper or lower case, not a combination.

■ If you leave the number off a command, zero is assumed. For example, if you

type

ATE, ATE0 is assumed.

A: Answer Mode

Causes the modem to attempt a handshake in answer mode.

D: Dial Number

Instructs the modem to go off-hook and execute the dial string which follows the D. Commands which may be part of the dial string are listed below. Any unrecognized character in the dial string is ignored. Once dialing is complete, the modem attempts a handshake in originate mode (unless the R parameter is given).

0-9 Any number simply dials that number. A, B, C, D, # or * (tone dial only) dials the indicated symbol. P Causes subsequent numbers to be pulse dialed. T Causes subsequent numbers to be tone dialed. R Forces the modem to dial a call in answer mode. W Causes the modem to wait for a dial tone using S7 as a time out.

AT Commands 29

, Causes a delay, determined by S8, before the modem proceeds with the

next command or digit. = Same as the ‘,’ modiﬁer except that the delay is doubled. ! Causes the modem to go on-hook for .5 second and then of f-hook for .5

second before continuing. @ Causes the modem to wait until it detects 5 seconds of silence before

continuing. ; Causes the modem to go to the command mode when the number is

dialed. In order to proceed with channel establishment mode ATO or ATD

must be entered. Any characters that follow this parameter are tr eated as

AT commands. ^ Do not send calling tone. # Causes a 0.5 second delay before the modem dials the digits (DTMF)

following this modiﬁer. L Causes the last telephone number that was dialed by the modem to be

re-dialed. S Causes the modem to dial the number in stored position "n" Format is

S=n or Sn. If S41 is set to a value other than 0, the modem will attempt a

maximum of S41 redials upon call failure. In error correction mode S38

dictates the delay before terminating a call (matched with S10).

E: Echo Commands

Deﬁnes whether characters are echoed back from the modem to the DTE when in command mode.

E0 Command echo inhibited. E1 Command echo enabled.

H: Hook Switch Control

Controls the modem’s hook switch relay.

H0 Terminates a call. H1 Causes the modem to go off-hook.

I: Interrogate Modem Status

I0 Requests the modem code. I1 Requests that a checksum calculation be performed on the software

ROM. The answer is displayed as four hexadecimal digits.

30 CHAPTER 5: USING THE MODEM

N: Handshaking

Selects whether a connection will be forced to a speciﬁc speed.

I2 The modem performs a ROM checksum, compares the result against a

stored value, and returns an OK or ERROR message depending on the

success of the comparison. I3 The modem sends its ROM Part Numbers and Revision Levels. I4 The modem sends its ASCII string test. I5 The modem sends its data pump chipset revision. I7 The modem sends platform speciﬁc information.

N0 Sets the required connection speed to that set under S37. N1 If S-register S37 is not equal to 255 it allows handshaking at the highest

speed supported by both modems. If S-register S37 equals 255 it allows

handshaking at the highest speed supported by both modems and DTE. N2 If S-register S37 is not equal to 255 it allows handshaking at the highest

speed deﬁned by S37. If S-register S37 equals 255 it allows handshaking

at the highest speed supported by both modems and DTE.

O: Return to On-Line State

Applicable when a physical connection with a remote unit exists and the modem is in the on-line command state.

O0 Returns the modem to the on-line state. O1 As O0 except that when a 2400 bits/s or higher connection is established

an equalizer retrain sequence is transmitted.

Q: Return Result Codes

Deﬁnes whether the modem will issue result codes to the DTE.

Q0 Result codes returned. Q1 Result codes not returned. Q2 Result codes returned in originate mode only.

V: Verbose mode

Deﬁnes the form of result codes returned by the modem.

V0 Numeric form responses enabled. V1 Verbose responses enabled (English responses).

AT Commands 31

W: Connection Result Codes

Deﬁnes the type of (extended) negotiation result codes to return.

W0 Negotiation codes not reported. W1 Negotiation codes reported in 3 line format (Hayes format). W2 Negotiation codes reported in 1 line format (Microcom format). W3 Negotiation codes reported in 1 line format (Microcom format). The

receive and transmit bit rates will be displayed, Rx/Tx bit rates.

X: Result Code Set/Call Progress

X0 Causes the modem to ignore any network tones and omit the connection

speed message. X1 As above but enables the connection speed result codes. X2 Causes the modem to detect dial tone. X3 Causes the modem to detect busy tone. X4 Causes the modem to detect busy and dial tones. X5 Causes the modem to report ringing, to detect busy but dial tone is

ignored. X6 Causes the modem to perform adaptive dialing (automatically determine

if dialing can be performed using DTMF signaling), to report ringing, to

detect busy and dial tones.

Z: Recall User Conﬁguration

The user conﬁguration stored in non-volatile memory is recalled to become the active conﬁguration.

Z0 Resets modem and recalls user proﬁle 0. Z1 Resets modem and recalls user proﬁle 1. Z2 Resets modem and recalls user proﬁle 2. Z3 Resets modem and recalls user proﬁle 3. Note: The actual amount of proﬁles depends on the size of the non-volatile

memory that a platform contains.

32 CHAPTER 5: USING THE MODEM

S Registers AT command settings are stored in S Registers. S-register values can be changed

by AT command or by entering the new value of the S Register, preceded by AT. The command ATSn=v changes register n by setting its value to v.

For example, to change from manual answer to auto-answer after three rings, follow these steps:

1 Check the S Register table for the register that controls Answering. The functions

are listed in alphabetical order.

2 Start your communications software and enter Terminal mode. 3 Type ATS0=3 and press [Enter]. The modem will now answer a call after three

rings. All values are in decimal format. Default values indicated in bold type are those

written after execution of the &F0 command. If the register TYPE is Nonstorable, this default value will also be written whenever the modem is reset. For storable register, however, the value after r eset will be set to that stored in the appropriate stored proﬁle.

Modem Troubleshooting

Symptom Solution

COM Port Conflict Indicates a conflict between two drivers claiming the same IRQs.

Cannot hear modem or speaker

Error Message Make sure you selected the correct COM port in your software.

Change one of the IRQs. Remember that the modem interface of the LAN+Modem card is a Winmodem and uses COM5 or higher.

Make sure your computer's speaker is turned on (ATM1). Turn your speaker volume on (ATL3).

With the default audio settings for Windows 98, the sound may be disabled. To enable the sound, use the following procedure:

1 Locate the speaker icon in the system tray.

If there is no speaker icon in the system tray, open the Control Panel and double-click Multimedia. On the Audio page, make sure Show volume control on the task bar is checked

2 Double click the speaker icon in the system tray. 3 When the Master Out window opens, select Options. 4 Choose Properties and make sure the Mono In box is

checked. Click OK.

5 When the Master Out window is redisplayed, check Mono In

Balance. Ensure that the mute box is unchecked.

If you are typing from the command line in terminal mode, retype the command.

Make sure you are issuing the correct command.

Modem does not dial correctly

Modem not responding Check your computer's BIOS setup. If it requires certain settings

Make sure you have entered the telephone number correctly if you are using the dialing directory.

Make sure the number you dialed is correct if you are dialing it in terminal mode.

Be sure you added any required prefix (such as 1) before your number when dialing long distance.

The other line could be busy or not answering. Make sure it is available to answer before calling.

If you are dialing internationally, your modem may not recognize the dial tone. Try the command ATX3DT and the telephone number.

for modems, be sure they have been turned on. Make sure you have selected the correct COM port in your

software setup. Make sure the modem has been connected completely. Check

all your connections and make sure they are all secure. Reboot your system.

Modem Troubleshooting 53

Modem does not dial Check your phone line and cable connections. See “Installing

Modem cannot connect to remote access server.

Modem does not fax Make sure you have selected the correct fax class.

Modem does not connect

and Connecting the Card” on page 1. Make sure no other phone extension has been picked up on the

same line. Make sure you are using a standard analog telephone line. You

might receive an error if you are trying to connect to a digital phone system or PBX.

Listen for a normal dial tone on the line. If the dial tone sounds different than normal, find another line.

When connecting to a remote access server running V.34 protocol (up to 33.6 Kbps) with devices such as 3Com Access Builder, configure your DUN settings to reflect the connection speed. We recommend 19200 or 38400 Kbps. Settings of 57600 or 115200 Kbps will cause a failure.

Make sure that you do not have another communications program open.

Be sure you selected the correct printer driver in your word processing program.

Turn off all power management. Make sure the parity, modem speed, word length, and stop bits

are set up according to specifications. Try removing all of the error correction and data compression.

No Dial Tone Message Check all the cable connections and make sure they are secure.

Digital Line Error

Message Modem clicks

The connection to the phone line could be incomplete, or the phone cable could be bad.

Make sure the telephone line you are using is not in use by someone else.

Check to make sure you are using a standard analog telephone line. If you are trying to connect to a digital phone system or a PBX, you may receive an error message.
