Dell Modem Diagnostic Tool is a Windows application used by customers and Dell Tech support to diagnose modem hardware and software problems. It helps identify the most common modem failures.
This new tool replaces the Modem Helper utility, however opposite to Modem Helper, it doesnt support all model brands.
Basically the Modem Diagnostic tool, accomplish the following:
Compares the file copy section in INF to the system files.
Compares the registry entry info in INF to the system registry.
Checks the driver status in Device Manager.
Verifies the modem hardware PnP ID.
Verifies the modem hardware can respond to AT commands.
Verifies the modem hardware can communicate with the host computer.
Verifies the modem hardware can detect a dial tone.
When the Modem Diagnostic Tool tests the modem driver, it performs the following operations:
Compares the modem registry entries in the modem INF files to the system registry settings.
Compares the file copy section in the modem INF files to the system files and their locations.
Verifies the modem status in Device Manager and checks for any warning signs.
While an average pc user wont know what I have described above, most of the time it provides an accurate and easy to understand error message, its web user interface make it accesible and avoid complications if we compare it with other diagnostic tools that requires Microsoft Net Framework or Sun Java Runtime Environment.
If you are a Dell customer and still use a dial up connection, its highly recommended to use this tool.
