Modem Control Panel in Win 2000:

Links on this Page: General Tab | Diagnostics Tab | Speed, Flow Control & Init Strings | Update Driver | Reinstall |

The Phone and Modem Options applet of the Control Panel allows to add initialization strings, view modem settings and run modem diagnostics. 

Click the Start button, then Settings, then select Control Panel as pictured below.

Double click on the Phone and Modems icon, pictured in the middle of the Control Panel below.

After clicking the Phone and Modem icon to open the modem properties, the following screen appears.

 

"Modems Tab" of the "Phone and Modems Options":

Select the Modems tab to access additional modem options.  The Modem tab of the lists any modem installed on your computer.  You should only see one modem listed here.  It is possible to have more than one modem physically installed on your computer, but almost nobody ever does.

A "Ghost" modem is a modem driver with no corresponding hardware.  This means you have a driver installed for your modem, but the modem itself is not installed in the computer.  The image below shows only one modem installed, and this is as it should be.  If there were a second modem listed, one of these would be a "ghost" modem.  Examples of what might be listed here include: 
    LT Win Modem #2      <--Note the #2 at the end.
    Standard 56K Modem
    etc.

To determine which modem is the good modem and which is the "ghost" modem, highlight the modem, click Properties and then go to the Diagnostics tab.

Even if you do not have a "ghost" modem, click Properties so you can go to the Diagnostics tab to find out if your modem is working properly.

Click Properties to open the following window.

 

General Tab:

The General tab will be the first tab displayed.  It is a good idea to set the Maximum Port Speed as close to your modem's actual speed.  So, for a 56k modem this would be 57600.  Leave the checkmark in "Wait for dial tone before dialing".  Otherwise, you may get busy signals or "no dial-tone" errors.

Important:  Since the DUN properties will override these settings, changes must be done from within the connectoid.  Already existing connections will not be affected by changes in the Control Panel.

 

Diagnostics Tab:

Click the Diagnostics tab across the top to see the screen below.  Initially, the "Command/Response" field will be blank.  Click the Query Modem button to run a diagnostic.  

If everything is ok, a list of commands starting with the letters "AT" will be displayed as shown below.  This output tells you that the computer and the modem can communicate, which means that at least the hardware of the modem is functioning.  This means that you may only need to update the modem driver.  
Click here to drop to the section for help updating modem drivers.

Note that the line displayed after "ATI3" typically shows the full name and Driver version for your modem.

If the computer cannot communicate with the modem, an error message will pop up.  If you are trying to determine which of two modems is a "ghost" modem, this is it.  Go back to the General tab and remove it.  Or, if this is the only modem, this may indicate a hardware problem with the modem.  Hopefully, it's only a problem with the driver.  It's time to remove and reinstall the modem.  
Click here to drop to the section for help reinstalling a modem.

 

Advanced Tab:  Speed, Flow Control, & Init Strings

Click on the Advanced tab to see the image below.  Here, advanced users can add initialization strings to change the operation of your modem.  These are typically not required, but can be useful in correcting connection problems.  Don't do this unless you know exactly what you are doing. A bad init string can cause your computer to think that there is no modem installed. It can also cause that modem to not work correctly.  Consult your modem documentation or contact our ISP for help.

If you have an internal 56k modem and you just can't get a stable connection due to your phone lines or your modem software, you might want to fix that problem by putting in a V34 init string. This will cause your modem to connect at only 34 kbps but at least you'll have a reliable connection. The two most popular V34 init strings are AT+MS=V34 or ATS37=19. Only use one of them and don't put in any extra spaces.

Click on Change Default Preferences to see the screen below.

You can change the Call preferences according to your taste.  

The Data Connection Preferences is where you can set the speed and flow control.  It is better to change these settings from within the actual connection.  Click here to go to the Existing Connection section for help with this.

Click the Advanced tab to see the screen below.  The default settings of 8, None, 1, Standard should be left alone.

Click 'OK' to return to the Advanced tab.

This covers everything in the Phone and Modem Options applet of the Control Panel.

 

 

Update Modem Drivers:

Installing modem drivers is easy, but it's actually the second step.  The first step -- finding the driver -- is the more difficult step, and is the subject of it's own page.  Click here for help finding drivers.  Once you've found the correct driver, you can install it on your computer.  

If the driver is an executable program (file extension is .exe), then simply click on the .exe file to install the new driver.  Most PC Manufacturers package their drivers this way.

If the driver file is not an .exe, you will have to install it the old fashioned way, as described in the rest of this section.  

Note:  Files may be in .zip or .rar formats, which means you will have to "unzip" or "extract" the files before installing. 

To update modem driver software or view modem settings, click the Start button, then Settings, then select Control Panel as pictured below.

Double click on the System icon, pictured at the the bottom of the Control Panel below.

 

After clicking the System icon to open the system properties, select the Hardware tab, as shown below.

Click the Device Manager button.

The Device Manager window is pictured below.  Click the + sign next to Modems to expand the tree.  Right-click on your modem and select Properties from the pop-up menu.

When the Modem Properties opens, click the Driver tab to see the screen below.

You can view the view the file version of your driver by clicking on the Driver Details button. A screen like the following one will appear.

Click 'OK' to get back to the main Driver tab.

If you determine that you need to upgrade your modem driver, click the Update Driver button to start the Update Wizard.

Click 'Next' to continue the upgrade Device Driver Wizard. 

Choose the last option, Display a list of the known drivers for this device so that I can choose a specific driver.  Then click 'Next'.

Here you will click on the Have Disk button.  You will be prompted for the location of the file.  

Browse to the location where you have stored the driver for your modem and click OK.

After installing, click 'Next' and your modem driver will be updated with the new software.

 

 

Add or Reinstall a Modem:

If you're getting a lot of modem errors, such as "cannot open port", "port already in use", "cannot communicate with modem", then you may need to completely reinstall the modem.  You can run a diagnostic to see if the computer can actually communicate with the modem.  (Click here to jump to section above with this info.) 

Reinstalling  a modem is easy, but it's actually the second step.  The first step -- finding the driver -- is the more difficult step, and is the subject of it's own page.  Click here for help finding drivers.  Once you've found the correct driver, you can safely remove and reinstall the modem on your computer.  

IMPORTANT:  Make sure you have downloaded the most up to date driver from the Internet before continuing.  

Once you have the correct driver, follow the instructions below to remove and re-install your modem.

 

Click the Start button, then Settings, then select Control Panel as pictured below.

Double click on the Phone and Modem Options, pictured in the middle of the Control Panel below.

After clicking the Modem icon to open the modem properties, the following screen appears.  Select the Modems tab.

Click Remove, and then reboot your computer.  When it restarts, Windows 2000 should automatically find your modem and try to install the driver.  If it doesn't, try rebooting again.  You can also go back to the Phone and Modem Options (above) and click Add.  Either way, you should eventually reach the screen below.

Click 'Next' and Windows 2000 will locate and install your modem.

-Or-

If you have new modem software (driver) that you prefer to install, choose Don't detect my modem; I will select it from a list.  The following screen appears.

Click the Have Disk button.  You will be prompted for the location of the file.  

Browse to the location where you have stored the driver for your modem and click OK.  

Then click Next to arrive at the following screen.

After you have selected the file, choose which port to install the modem on.  Any of the COM ports are typically okay to use.  Try to pick one that is never used by another device (like a mouse, camera, joystick, etc.). Click Next.

It may take a few minutes for Windows 2000 to install your modem.

After Windows 2000 installs the modem, click Finish to exit the Wizard.

You have now successfully reinstalled your modem.
