Troubleshooting

POSSIBLE SOLUTION

You may have a COM port/IRQ conflict. If you have an internal modem and a Windows 95 system, right-click on the My Computer icon on your desktop. Click Properties. Click the Device Manager tab. If you see a yellow exclamation point over your modem, you have a resource conflict, and it is probably an IRQ conflict. Click the modem’s name to select it. Then click Remove. You will be asked if you are sure you wish to remove the device. Click OK. When the modem has been removed, shut down and turn off your computer. Unplug the computer from its electrical outlet and remove the cover. Physically remove the modem from its ISA slot. Replace the cover, plug the computer back into the electrical outlet, and turn on the computer. When Windows restarts, once again right-click the My Computer icon on your desktop and click Properties. Click the Device Manager tab. Double-click Computer. Make sure the “Interrupt request (IRQ)” radio button at the top of the screen is checked. You can determine which IRQ settings are free on your system by looking for numbers that are not listed in the Setting column. One of the following IRQs needs to be free: 3, 4, 5, or 7 (or 9 if you have a Winmodem). If there are no IRQ settings free in this range, you need to move a device off of one of these IRQs in order to free it for use by your modem. We recommend removing other modems or disabling COM ports that may be using one of these IRQs. After you have made these changes, reinstall the modem using the instructions in the Installation Guide. Once your modem is properly installed, make sure you have the correct COM port and IRQ settings in your software and/or in the Windows Device Manager.

PROBLEM: The modem will not go off hook to dial or does not answer the phone.

POSSIBLE SOLUTION

You may have plugged your modem’s phone cord into a digital line. Plugging your modem’s phone cord into a digital phone line can damage the modem. Call your phone company if you are unsure whether or not your phone line is digital.
