Serial external modem problem

by phil66 / June 23, 2006 10:23 PM PDT

I need to purchase another Serial external dial-up modem for a new PC with Windows XP Home and Linux operating systems.
My Zoom serial external modem with the latest updates when installing will get a notice from XP that continuing the installating will cause harm to my computer now or later.This modem will stay on my old PC.

I have found a US Robitics serial modem 56k v.92 part # usr5686e that shows to be Windows compatible.

Does any one have knowledge about the Robotics modem is it really compatible and will it eliminate the pop up from Windows about harm to my computer.

Where can I search in Microsoft to find compatible modems? I am unable to find a compatibility chart.

Why do you want an extermal modem?

USR makes good products and all modems are supposed to be compatable with today's OSs.

I have had (3) modems on this computer. The serial external is the fastest of all the three and it also handle Linux Distro's with ease.
No real reason only personnal choice.

Call it a Hayes model that's in the supplied drivers and it still works. Or if the message is about "XP Certified" consider that getting that message is a money issue. You have to pay Microsoft for the certificate. With low volume products, no one bothers and asks the owners to press the button to install the driver.

Hi Ray

I have not encountered such a message as you mention, regarding damage to the PC on connection of a piece of hardware, especially serially connected hardware and until this is understood, I would be reluctant to try or buy anything else. What is the actual message, and have you searched for this on the web directly?

Have you checked for other modems registered in the drivers list )has the new PC already got an internal modem for example)?

I know that Trust do good modems, whhich seem to work on a range of PCs but it doesn't sound like the problem is with the modem.

Generally, XP should be happy with any serial device, and indeed most common modems should work more or less immediately after plugging them in (the installation disk usually includes add-ons like faxes etc)

Thanks for the reply
When I originally bought this modem I installed it on a Windows ME system. There was no warning on ME

Purchased a XP computer without a modem and when I started to install I got the message
To summarize the message The install was not review by Microsoft and the fee for such had not been paid. The actual hardware is not being questioned just the installer.
Zoom is one of the company's that refused to all M$ to review there installed and pay a fee.

Is USR5686e Compatible with Windows XP
by cward / June 24, 2006 12:46 AM PDT

Yes, your modem model is compatible with Windows XP.

Check Windows XP to ensure that your system com ports are available in Windows by doing the following:

Right mouse-click the My Computer Icon
Double click ports from the list of devices
Communications ports 1 and 2 should be displayed

If not, the port(s) could be disabled in your system bios and not available to Windows. If this is the case you will need to enable the port(s) in the bios.

Windows XP typically displays the "terror warning" if it detects a device that it can't read plug & play bios information from. I seriously doubt that harm will come to your system by installing an external modem. Try doing a manual installation (download the latest drivers from 3COM for your modem). Or, you could manually select a Windows generic driver for the modem (if you don't find that particular model listed by Windows).

Good Luck

All systems are go only needed a modem that the installer would not give a warning.
The Robotics modem has a picture of the Windows logo next to it. Time will tell if there installer has been reviewed by M$.

Thanks for the reply and good info.
