If you have a modem connected to or installed in your PC, when you install Windows 98 with the modem on, Setup will probably automatically recognize and install support for the modem. If you change modems or add a new modem, you can use the Modems object in the Control Panel to install support for the modem yourself. To install a new modem, open the Control Panel and choose the Modems object. From the General page of the Modem Properties sheet, choose the Add button. Windows 98 starts a modem installation wizard. You have two options for installing the modem. By default, the wizard automatically scans your PC's COM ports for a new modem. Or you can place a check in the check box labeled Don't detect my modem, which enables you to choose a modem from a device list.
If your modem is installed and turned on (if, for example, you have an external modem), leave the check box cleared, which enables the wizard to search for the modem. If you have not yet installed the modem, place a check in the check box, which bypasses the detection phase and enables you to select your modem from a list. If you direct the wizard to detect the modem and the wizard doesn't find a new modem, the wizard will tell you it can't find a new modem and displays this same dialog box, enabling you to select the modem manually.
Search through the Manufacturers list to select your modem's manufacturer; then select the model from the Models list. If the list doesn't include your modem, select Standard Modem Types from the Manufacturers list and select the model from the Models list that matches the maximum speed of your modem. If yours is a 28.8kbps modem, for example, choose the 28,8000 model from the Models list.
If your modem isn't listed, it might be compatible with a model from another manufacturer or with a different model from the same manufacturer because the command sets for the modems might be the same. Choosing a compatible modem rather than one of the standard types could make additional features available that the standard models don't support. If you can't find a compatible model, however, the standard types should provide adequate support in most situations. Or you can check with the your modem's manufacturer to determine whether the manufacturer has a Windows 98 driver available for your model or can suggest a compatible selection. Check the modem's manual to determine whether it is compatible with a specific type of modem.
After you specify the modem model and click on Next, the wizard prompts you to specify the port to which the modem is connected. Choose the appropriate port; then click on Next. The wizard then copies any required files and installs support for the modem.
You can install multiple modems for a single COM port. When you configure a Win32 application that uses the Windows 98 communications Application Program Interfaces (APIs) and Telephony Application Interface (TAPI), you select which modem to associate with the application. Installing two or more instances of the same modem driver enables you to use different sets of settings for various applications. You might configure one set of settings to use compression, for example, but configure another to disable compression.
