GENERAL FAQ

Question:   How to configure DataBridge faxmodem parameters in ISP software?                

Answer:     In ISP software, in modem setup submenu, please choose ``Generic" or ``Standard (Hayes Compatible)" from the modem list to configure your DataBridge faxmodem.

Question:   What type of Faxmodem should I choose when I install Communication Software?

Answer:     You can select as: Modem Type - Choose Hayes Compatible; Fax Type - choose Generic Class 1 or 2.

Question:  Why did I get a `` Modem not found " message?

Answer:     Possible COM port / IRQ conflicts. Most computer have two serial ports on the back panel. These are recognized by the computer as Com1 and Com2. A conflict occurs when the modem is configured on either of these ports. To remedy this, set the modem up for Com3 with IRQ5, or Com4 with IRQ3. Availability of these ports/IRQs depends on the configuration of the system.

Question:  Why does my mouse act erratically while attempting to use the internal modem?

Answer:    Typically this occurs after the modem initializes, but also occurs upon installation. It is because of IRQ conflict. Remedy: set modem for Com3 with IRQ5, or Com4 with IRQ3.

Question: How to enable error correction / data compression?

Answer:    Use the initialization string: AT&F&C1&D2 for most software.

Question:  What class fax modem do I have?

Answer:     If you have a 9648 fax modem ( internal or external ), it is a Class 1 fax modem, all the other fax modems are class 2.

Question:  Why can't I fax?

Answer:     Possible Com / IRQ conflicts. If your modem is using the same IRQ as another device, ( Sound card, CD-ROM drive, etc. ). To remedy this, set the modem up for Com3 IRQ5, or Com4 IRQ3. Availability of these ports / IRQs depends on the configuration of the system.

Question:  Why is there Garbage on the screen during a modem data call?

Answer:     Three common explanations: 1. Line noise on the phone line; 2. If most text appears normally, but with some ``machine code" every few sentences or so, make sure the terminal emulation is set to ANSI ( This occurs most commonly while on-line with BBS systems which support ANSI graphics.) 3. If lines of ``machine code" are going across the screen, with little or no readable text, the modem's error correction is not turned on: using the initialization string: AT&F&C1&D2 for most software. 

Question:   How do I download files from BBS?

Answer:     Downloading procedures begin with the selection of a file to download. Once the file is selected, the BBS will prompt for a download protocol. Usually a list of supported protocols will appear. Select a protocol which is common to both the BBS and your system. Most BBS system will then display the estimate time for the download and a command that can be used to abort the download. The BBS then waits for your system to initiate the download. At this time, the user must tell their system to receive a file, specifying which download protocol ( the same protocol that was selected on the BBS ) and file to receive. The user's system then starts downloading.

Question:   Why do I get a ``No Dialtone" message ?

Answer:     There are three most common causes: 1. Is the phone cord plugged into the proper jack on the back of the modem? The cord should go between the telephone  wall jack and the LINE jack on the modem. If a phone is to be used in conjunction with the modem, plug it into the PHONE jack on the modem. 2. Modem being used on a business PABX system on which special code or other action is required to get an outside line. 3. Bad phone cord. Use the phone cord supplied with the modem.

Question:   How do I get a received fax into a word processor to edit the text?

Answer:     It is not possible to edit received faxes in either Winfax Lite or Quick Link. In order to edit faxes, it is necessary to use a fax program with OCR ( Optical Character Recognition ). Such program are available, but not shipped with the modem. 

Question:   How does Voice/Fax/Data Automatic Detection work?

Answer:     The issue of V/F/D Detection has been addressed by Quicklink. This is a feature of the SOFTWARE, not the modem HARDWARE. If Auto Detect is enabled, Quicklink will answer all incoming calls.

Question:   My faxmodem keeps disconnecting from my ISP, what should I do?

Answer:     There are two main causes of modem disconnect: Inactivity Timeout and Line Noise causing a modem retrain. If you are reading a web page and not actively doing anything other than scrolling up or down, the Inactivity Timer can disconnect you.  If you are having irregular disconnect problems ( immediate disconnect, or random disconnect), you will want to alter your modem's initialization string to the following: AT&FX4#F0$R1%E0. This string will make sure your modem doesnot initiate a speed change while connected to the ISP's modem. Your modem will, however, follow any speed change that the ISP's modem makes. This will ensure that your modem does not cause a disconnect.

Question:   What should I do if the modem does not answer an incoming call?

Answer:     Auto-answer may not be enabled. If expecting a call from another modem, you must set up your modem for answer mode. Refer to the procedures for answering a modem call in your software's user's guide. The incoming call may not be from another modem. You may have a faulty phone jack or the phone cable may not be connector on the same circuit if the circuit is operating properly. After setting your modem answer mode, you can also try to calling the modem number from another telephone line to listen for the modem's answer tone ( a high-pitched whistle ).

Question:   Why does my modem connect at 26,400 BPS or slower when making a V.34+ connection in some time?

Answer:     Telephone line signal quality varies widely from one area to another and from one call to the next. All V34+ modems probe the telephone line during the initial ``handshake" sequence to determine the optimum carrier speed to utilize based upon the quality of the received signals. DataBridge faxmodem feature the most robust V34+ technology available today and will connect at the highest possible speed. When calling local numbers, your modem should typically connect at speeds of 26,400 to 33,600 bps. When calling long distance numbers, connect speeds may vary between 19,200 and 28,800 bps.

Question:   Why is my Plug and Play faxmodem not detected by Windows 95?

Answer:     The most common cause for a DataBridge internal Plug and Play modem not to be detected by Win95 is improper seating of the modem into the motherboard connector. Power off the computer and verify that the modem is properly seated to its ISA bus connector on the motherboard. Be sure to attach the bracket holding screw to the modem bracket to secure the modem in its peripheral slot. After that, power up the computer and follow the on-screen directions provided by Win95 to install the faxmodem configuration diskette that came with your modem.

Question:   Are there certain times when I will not to be able to achieve a connection rate of 56k?

Answer:     To achieve 56k, you must connect to an internet service provider or service that supports 56k plus.

Question: How do I un-install my existing slower speed modem?

Double-click `My Computer', double-click `Control Panel', then double-click `Modems'.  Click on the name of the existing modem and click `Remove'.  When you are asked to confirm, click `Yes'.  You are now ready to remove the existing modem in your computer.

Question: How come my computer cannot detect the modem?

Possibly you might have a COM port and IRQ conflict with another device or modem.  To detect and solve COM port conflict: For Win 95/98, click `Start' then to `Setting'.  From `Control Panel', double click `Modems'.  Check if any other modems are already installed in your computer.  Check each one of them for COM port and IRQ info. by choosing `Diagnostic'.   Delete or un-install the modem you don't want then reinstall the modem you need.

Or: Click `My Computer' icon, then `Properties'.  From `Device Manager', double click `Ports'.   If you find a yellow exclamation point or a red `X' over them, your COM port may be set up incorrectly, please adjust or reinstall.

COM port/IRQ issue with Windows NT:

For COM port: please check the COM port addresses to see if they are in use, assign the modem to a free COM port.

FOR IRQ issues: Click Windows `Start' button, go to `Administrative Tools'.   From `Windows NT Diagnostics' go to `Resources' and select IRQ. 

Write down the IRQ available for usage,  if no IRQ is available, please free a device for additional IRQ usage.

*** Also see Q & A for `No dial tone' solution or see `How come my software cannot detect the modem?'.  Make sure the modem is installed completely & firmly, you should not see any part of the gold edge.

Question: How come my software cannot detect the modem? 

1.Check Windows in `Modem', to determine what COM port was set then double check with software set up for current COM port. Please make sure they match.

2.Set up your modem type correctly in software, usually `Hayes Compatible', `Hayes Compatible with error correction' or `Standard Modem' will be suitable.

3.When using a Dial-Up-Networking software, make sure the correct modem is selected by double clicking `My Computer', then `Dial-Up-Networking'.  Right-click the connection you are trying to use, then click `Properties'.  Make sure the modem name is the same as the modem you are using.  If not re-select the correct one.

Question: How come my modem does not dial when I send a dial command?

1. Make sure you dialed a valid number and include all prefixes such as 9' if required. Also check the line you are dialing from is an analog phone line, not a digital line.

2. Make sure the line is securely connected.  Refer to the question: `Why do I get a No Dial Tone message?' or the solution for `How come my software cannot detect my modem?' in Q & A.

Question: The installation seems to be OK when I installed my DataBridge modem but the computer cannot find it later.

If you have a built-in modem in your computer, Windows may reinstalled it whenever you reboot your system.  Check with your computer manual to see how to disable the built-in modem.   Or reinstall modem in another PCI slot; there might be a problem with the first PCI slot.  If necessary, try all available slots. Also see solutions from `How come my computer cannot detect the modem?' and  `How come my software is not detecting modem?' in this Q&A.

Question: Why is it that I can't connect the modems at the maximum speed?

The are several reasons why modems cannot achieve their maximum capacity.  First, FCC regulations limit maximum download speed to 53k.  Second, the quality of your phone line affects the transmission speeds during any given connection.  Of course the older or poorer quality phone line you have, the slower the transmission speed.  Third, the  amount of memory and processor speed will also determine how fast your modem will transmit.  Moreover, the amount of traffic at the ISP end or at the web site you are visiting may also slow your download speed due to traffic congestion.

Here are some pointers that will help to optimize your modem performance:

*From `Control Panel', click the `Modem' icon.  Click `Properties' and change the setting to maxim speed at 115,200 or 230,000, also set up communication software to 115,200.    

*Or move the telephone line away from other devices or power source such as extension phones, cordless phone bases, monitor...etc and make sure your phone cord is not longer than 12 feet.

*Make sure your ISP supports V.90 or 56kflex, contact them to see if the number you dialed supports these standards.

*Add more memory or upgrade the CPU will help also.  Open only the application you need; too many opened programs will use up memory and CPU resources and slow down the overall system performance.

Question: How can I not miss important phone calls while I'm on-line?

Currently, when you are using the modem to go on-line, incoming callers will hear a busy tone or just the ring (with call waiting activated).  You can download an Internet Answering Machine software for free by going to  www.callwave.com.  The Internet Answering Machine works with the call forwarding feature of your phone line to answer calls while you are on-line. Once activated, callers no longer get annoying busy signals when you are on-line.  Instead, callers will hear a brief CallWave greeting after which they can leave a short message and that you will be able to hear instantly.

Question:  My fax modem keeps disconnecting from my ISP, what should I do?

There are two main reasons for the modem to disconnect: Inactivity and line noise.  If you are reading a web page and not doing anything other than scrolling up or down, the Inactivity Timer might disconnect you.  If you are having irregular disconnection problems (immediate disconnect or random disconnect), you will want to alter your modem's initialization string to the following: AT&FX4#F0$R1%E0. This string will make sure your modem doesn't initiate a speed change while connected to the ISP's modem.  Your modem will, however, follow any speed change that the ISP's modem makes.  This will ensure that your modem does not cause a disconnection.

Question:  Why do I get a `No Dial tone' message?

There are three common causes:

1. The phone cord plugged into the wrong jack on the back of the modem.  The cord should go between the telephone wall jack and the `LINE' jack on the modem. If a phone is to be used in conjunction with the modem, plug it into the `PHONE' jack on the modem.

2. Modem being used on a business PABX system on which special code or other action is required to get an outside line.

3. Bad phone cord. Use the phone cord supplied with the modem.

4. You might have too many devices connected to the phone line.  If so, remove all other equipment.

5. IRQ of the modem might be in conflict with another device or has been misreported to Windows.  If so, reset the COM port and IRQ or reinstall the modem into another PCI slot.

*Also see the other notes about why the computer (or software) cannot detect the modem for possible solutions.

Question: How come there is no dial tone when I try to make a connection?

This could be due to an improper phone line connection.  Make sure the phone line is securely plugged into the phone jack on the wall.  Also, be sure the phone line is connected to the proper jack on the modem.  The phone line from the wall jack should be connected to the modem jack labeled `LINE'.  The other modem jack labeled `PHONE' is for the telephone.

Question: The modem is dialing but got a recording saying `the call cannot be completed  as dialed'.

Check to see the number you dialed is correct and make sure to include any prefixes such as `9', if necessary, to dial out.

Question:  How do I configure DataBridge fax modem parameters in ISP software?                 

What type of fax modem should I choose when I install the communication software?

To set up your modem type in software, choose `Hayes Compatible', `Hayes Compatible with error correction' or `standard modem' will be suitable.

Fax Type - choose Generic Class 1 or 2.

Question: Why did I get a `Modem not found' message?

Possible COM port / IRQ conflicts. Most computers have two serial ports on the back panel.  These are recognized by the computer as Com1 and Com2. A conflict occurs when the modem is configured on either one of these ports.  To address this conflict, set the modem up for Com3 with IRQ5, or Com4 with IRQ3.  Availability of these ports/IRQs depends on the configuration of the system.

*** also see Q & A   `How come my computer cannot detect the modem?' and `How come my software cannot detect the modem?'.  Make sure the modem is installed completely and seated firmly.  You should not see any part of the gold edge.

Question: Why does my mouse act erratically while I'm using the internal modem?

Typically this occurs after the modem initializes, but can also occur upon installation. This is because of IRQ conflict.  Remedy: set modem for Com3 with IRQ5 or Com4 with IRQ3.

Question: How do I enable error correction / data compression?

Use the initialization string: AT&F&C1&D2 for most software.

Question: Why does my modem disconnect automatically when I'm on-line?

This could be the result of a loose connection, an incoming call or if your call waiting feature is enabled.  Check your phone line connection or disable call-waiting feature.

Question: Why can't I fax?

Possible Com / IRQ conflicts. If your modem is using the same IRQ as another device, ( Sound card, CD-ROM drive, etc. ). To correct this, set the modem up for Com3 IRQ5, or Com4 IRQ3. Availability of these ports / IRQs depends on the configuration of the system. (Check your Windows system manual for details).

Question: Why is there garbage on the screen during a modem data call?

Three common explanations: 1. Line noise on the phone line. 2. If most text appears normal, but with some `machine code' every few sentences or so, make sure the terminal emulation is set to ANSI (This occurs most commonly while on-line with BBS systems which support ANSI graphics.) 3.

Question: How come my modem does not dial when I send a dial command?

1. Make sure you dialed a valid number and include all prefixes such as 9' if required. Also check the line you are dialing from is an analog phone line, not a digital line.

2. Make sure the line is securely connected.  Refer to the question: `Why do I get a No Dial Tone message?' or the solution for `How come my software cannot detect my modem?' in Q & A.

Question: The installation seems to be OK when I installed my DataBridge modem but the computer cannot find it later.

If you have a built-in modem in your computer, Windows may reinstalled it whenever you reboot your system.  Check with your computer manual to see how to disable the built-in modem.   Or reinstall modem in another PCI slot; there might be a problem with the first PCI slot.  If necessary, try all available slots. Also see solutions from `How come my computer cannot detect the modem?' and  `How come my software is not detecting modem?' in this Q&A.

Question: Why is it that I can't connect the two modems at the maximum speed?

The are several reasons why modems cannot achieve their maximum capacity.  First, FCC regulations limit maximum download speed to 53k.  Second, the quality of your phone line affects the transmission speeds during any given connection.  Of course the older or poorer quality phone line you have, the slower the transmission speed.  Third, the  amount of memory and processor speed will also determine how fast your modem will transmit.  Moreover, the amount of traffic at the ISP end or at the web site you are visiting may also slow your download speed due to traffic congestion.

Here are some pointers that will help to optimize your modem performance:

*From `Control Panel', click the `Modem' icon.  Click `Properties' and change the setting to maxim speed at 115,200 or 230,000, also set up communication software to 115,200.    

*Or move the telephone line away from other devices or power source such as extension phones, cordless phone bases, monitor...etc and make sure your phone cord is not longer than 12 feet.

*Make sure your ISP supports V.90 or 56kflex, contact them to see if the number you dialed supports these standards.

*Add more memory or upgrade the CPU will help also.  Open only the application you need; too many opened programs will use up memory and CPU resources and slow down the overall system performance.

Question: How can I not miss important phone calls while I'm on-line?

Currently, when you are using the modem to go on-line, incoming callers will hear a busy tone or just the ring (with call waiting activated).  You can download an Internet Answering Machine software for free by going to www.callwave.com.  The Internet Answering Machine works with the call forwarding feature of your phone line to answer calls while you are on-line. Once activated, callers no longer get annoying busy signals when you are on-line.  Instead, callers will hear a brief CallWave greeting after which they can leave a short message and that you will be able to hear instantly.

Question:  My fax modem keeps disconnecting from my ISP, what should I do?

There are two main reasons for the modem to disconnect: Inactivity and line noise.  If you are reading a web page and not doing anything other than scrolling up or down, the Inactivity Timer might disconnect you.  If you are having irregular disconnection problems (immediate disconnect or random disconnect), you will want to alter your modem's initialization string to the following: AT&FX4#F0$R1%E0. This string will make sure your modem doesn't initiate a speed change while connected to the ISP's modem.  Your modem will, however, follow any speed change that the ISP's modem makes.  This will ensure that your modem does not cause a disconnection.

Question:  Why do I get a `No Dial tone' message?

There are three common causes:

1. The phone cord plugged into the wrong jack on the back of the modem.  The cord should go between the telephone wall jack and the `LINE' jack on the modem. If a phone is to be used in conjunction with the modem, plug it into the `PHONE' jack on the modem.

2. Modem being used on a business PABX system on which special code or other action is required to get an outside line.

3. Bad phone cord. Use the phone cord supplied with the modem.

4. You might have too many devices connected to the phone line.  If so, remove all other equipment.

5. IRQ of the modem might be in conflict with another device or has been misreported to Windows.  If so, reset the COM port and IRQ or reinstall the modem into another PCI slot.

*Also see the other notes about why the computer (or software) cannot detect the modem for possible solutions.

Question: How come there is no dial tone when I try to make a connection?

This could be due to an improper phone line connection.  Make sure the phone line is securely plugged into the phone jack on the wall.  Also, be sure the phone line is connected to the proper jack on the modem.  The phone line from the wall jack should be connected to the modem jack labeled `LINE'.  The other modem jack labeled `PHONE' is for the telephone.

Question: The modem is dialing but got a recording saying `the call cannot be completed  as dialed'.

Check to see the number you dialed is correct and make sure to include any prefixes such as `9', if necessary, to dial out.

Question:  How do I configure DataBridge fax modem parameters in ISP software?                 

What type of fax modem should I choose when I install the communication software?

To set up your modem type in software, choose `Hayes Compatible', `Hayes Compatible with error correction' or `standard modem' will be suitable.

Fax Type - choose Generic Class 1 or 2.

Question: Why did I get a `Modem not found' message?

Possible COM port / IRQ conflicts. Most computers have two serial ports on the back panel.  These are recognized by the computer as Com1 and Com2. A conflict occurs when the modem is configured on either one of these ports.  To address this conflict, set the modem up for Com3 with IRQ5, or Com4 with IRQ3.  Availability of these ports/IRQs depends on the configuration of the system.

*** also see Q & A   `How come my computer cannot detect the modem?' and `How come my software cannot detect the modem?'.  Make sure the modem is installed completely and seated firmly.  You should not see any part of the gold edge.

Question: Why does my mouse act erratically while I'm using the internal modem?

Typically this occurs after the modem initializes, but can also occur upon installation. This is because of IRQ conflict.  Remedy: set modem for Com3 with IRQ5 or Com4 with IRQ3.

Question: How do I enable error correction / data compression?

Use the initialization string: AT&F&C1&D2 for most software.

Question: Why does my modem disconnect automatically when I'm on-line?

This could be the result of a loose connection, an incoming call or if your call waiting feature is enabled.  Check your phone line connection or disable call-waiting feature.

Question: Why can't I fax?

Possible Com / IRQ conflicts. If your modem is using the same IRQ as another device, ( Sound card, CD-ROM drive, etc. ). To correct this, set the modem up for Com3 IRQ5, or Com4 IRQ3. Availability of these ports / IRQs depends on the configuration of the system. (Check your Windows system manual for details).

Question: Why is there garbage on the screen during a modem data call?

Three common explanations: 1. Line noise on the phone line. 2. If most text appears normal, but with some `machine code' every few sentences or so, make sure the terminal emulation is set to ANSI (This occurs most commonly while on-line with BBS systems which support ANSI graphics.) 3. If lines of  `machine code' are going across the screen, with little or no readable text, the modem's error correction is not turned on.

Use the initialization string: AT&F&C1&D2 for most software. 

Question:  How do I download files from BBS?

Downloading procedures begin with the selection of a file to download. Once the file is selected, the BBS will prompt for a download protocol. Usually a list of supported protocols will appear. Select a protocol which is common to both the BBS and your system.  Most BBS system will then display the estimate time for the download and a command that can be used to abort the download. The BBS then waits for your system to initiate the download.  At this time, the user must tell the system to receive a file, specifying which download protocol (the same protocol that was selected on the BBS) and file to receive. The user's system then starts downloading.

Question:  How do I get a received fax into a word processor to edit the text?

It is not possible to edit received faxes in either Winfax Lite or Quick Link.  In order to edit faxes, it is necessary to use a fax program with OCR (Optical Character Recognition).  Such program are available, but not shipped with the modem. 

Question:  What should I do if the modem won't go off hook to dial or does not answer a modem dial in?

Auto-answer may not be enabled.  If expecting a call from another modem, you must set up your modem for answer mode.  Refer to the procedures for answering a modem call in your software's user's guide.  Also review the software manual to see what DTR operation are required.  The incoming call may not be from another modem.  You may have a faulty phone jack or the phone cable may not be connected on the same circuit if the circuit is operating properly.  After setting your modem to answer mode, you can also try to call the modem number from another telephone line to listen for the modem's answer tone (a high-pitched whistle).  Also make sure the phone cable connect to the `LINE' jack and the telephone is connected to the `PHONE' jack on modem card.
