Windows XP diagnostics to resolve modem problems tips!

Use Windows XP diagnostics to resolve modem problems:
Although a surprising number of modem problems are related
to phone line issues, modem failures can also be caused
by incorrect settings or by damaged hardware. In this
article, I’ll discuss some methods that you can use
to troubleshoot these types of modem issues in Windows
XP.
Checking your modem properties
Once you’ve verified the integrity of your phone
line, the next step is to verify that Windows recognizes
your modem and that Windows can communicate with your
modem. Fortunately, Windows XP has some built-in diagnostic
utilities to help you accomplish these tasks.
To diagnose your modem’s problem, open the Control
Panel and click on the Performance And Maintenance link,
followed by the System link. When you do, Windows will
open the System Properties sheet. Select the Hardware
tab and then click the Device Manager button. The Device
Manager contains a list of all of the hardware devices
contained within your system.
Now, navigate through the Device Manager tree until you
locate your modem. Right-click on the modem and select
the Properties command from the resulting context menu.
Doing so will reveal the modem’s properties sheet.

On the properties sheet, check the General tab to make
sure that the modem is enabled, as shown in Figure A.
The General tab also contains a Troubleshooting button
that you can click to launch a troubleshooting wizard
that can guide you through a basic troubleshooting process.
Be sure the volume is turned up: Go look at the
properties sheet’s Modem tab to make sure that the
modem’s volume is turned up. Being able to hear the
modem during the dialing and handshaking process is often
helpful. For example, on many occasions, I’ve been
able to tell that there is no dial tone on the line just
by listening to the dialing process. You should also check
the Modem tab to make sure that the port speed is set
correctly. WinXpFix.com
Query the modem
At this point, you should select the Diagnostics tab and
click the Query Modem button. When you click the Query
Modem button, Windows will send a series of sample commands
to the modem. After a minute or two, Windows will display
a summary of the commands that have been issued and the
results of the commands, as shown in Figure C. You should
look through the list of commands for any errors that
may appear in the Response column. If errors do show up,
it could be a hardware conflict, a damaged modem, or an
invalid device driver.
Resolving a hardware conflict
If you suspect a hardware conflict, the next place to
check is the Resources tab. Most of the time, if the modem
is conflicting with another hardware device, there will
be a reference to the conflict on the Resources tab. In
addition to telling you which other hardware device the
modem is conflicting with, the Resources tab will also
tell you which resources (such as IRQ and Base Memory
Address) are conflicting. On some systems, you can resolve
such a conflict by deselecting the Use Automatic Settings
check box.
After doing so, you’re free to select the conflicting
resource and then use the Change Setting button to assign
a new set of resources to the modem. Just keep in mind
that not all available resources will work with all modems.
It’s usually better to let Windows XP select its
own resources if at all possible. WinXpFix.com
