5.2.1 Error Messages in Windows 98

In Windows 98 no error messages are returned directly.

Thus error conditions are not visible until an application

has been opened. Possible error messages include

“CAPI not installed” and “Error 680: no dial tone”, a

message from Windows Dial-Up Networking.

Possible solution: Check the Controller configuration in

the Windows 98 Device Manager. The Device Manager

is opened via “Start / Settings / Control Panel / System”.

The entry “AVM ISDN-Controller” displays all ISDN-

Controllers installed. Double-click on an ISDN-Controller

entry to view the properties of the device. The page lists

all resources currently assigned in the system including

I/O addresses and interrupts. Any resource conflicts in

the system also will be displayed. Should any conflicts

exist, change the Controller configuration accordingly

here. See also Chapter 3 for allocating resources.

5.2.2 Error Messages in Windows 95

Error message: “No AVM ISDN-Controller with the confi-

gured I/O address found.”

Possible error source: The I/O address set with the

jumper on the Controller is different from the entry in the

Windows Control Panel (Device Manager), or the hardware

is not installed.

Solution: The I/O address set with the jumper must

match the entry in the Device Manager. Open the Device

Manager (“Start / Settings / Control Panel / System”) and

select the AVM ISDN-Controller A1. Click Properties

and then on the “Resources” page. Use the Change

Setting button to enter the I/O address corresponding to

the jumper position on the Controller. Restart Windows

for the changes to take effect.
