Reconfiguring a Windows Dial-Up Networking Connection
When you attempt to check your modem after configuration, or to configure a Dial-Up Networking connection, Windows may issue a “COM Port open” error message. This means that previously installed modem configurations using the same COM Port as the Actiontec 56K PCI Internal Modem may be interfering with its operation. This interference is most likely due to the presence of an old Dial-Up Networking configuration. The problem is easily corrected by following these simple steps.
Step 1 Double-click the My Computer icon located on the Windows Desktop screen.
Step 2 In My Computer, double-click the Dial-Up Networking folder icon. Find the dial-up profile for any old modem(s). Using your right mouse button, click once (1 time) on the icon to bring up the menu.
Step 3 Select Properties from the menu to bring up the Properties screen. In the Connect using box, select your new modem and then click the OK button. This will reconfigure the dial-up profile for the new modem. After you have clicked the OK button in the Properties screen, restart the computer. This should clear the “Open COM Port” error.
