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.
