Checking the Modem:
|From Windows XP START, select Control Panel.
This brings up System Properties.
Select the Hardware tab.
Then, select Device Manager
The Device Manager is displayed. In some cases, you'll only have 1 modem related entry (as below); with some PCI modems, a modem or PCI enumerator may also be involved. You can also test the basic operation of the modem from the Device Manager as shown below:
In Device Manager, the modem tree is expanded, the modem entry is right-clicked, then Properties is selected in the drop-down menu; The Diagnostics tab of the modem Properties box is selected; this pane includes a Query Modem button: if the modem is correctly installed, the box above the button will display a list of at commands and the modem's actual response to them when you click the Query Modem button.
