I have a friend that upgraded a dinosaur to XP recently. After the upgrade all of the hardware listed in the hardware manager shows that all hardware is working properly. When he tried to use the modem "it would not work". I walked him through checking the modem. I came up with this...AT# CLS = Command Not Supported. I was just wondering if anybody knows does this mean that this particular modem is not compatible with Windows XP? If not, what is the best way to trouble shoot this?

Hi and welcome to Geeks to Go. It may well be that the modem is not supported in WXP. See if you can find out the make/model of the modem and then go to the manufacturer's web site and check for a WXP driver. Also, you could go over to M$ and check their listing of WXP supported devices. If the modem is not WXP compatible, you can replace it with one that is. Cost is $20 to $50 depending on what you want. I had a similar problem when I upgraded a dynosaur from Win98 to W2K pro. It had a modem that was a combo sound card/modem and simply was not suppoted. I replaced the modem for $19.00 with one that is W2K/WXP compatible.

I'll do some more investigating. Thanks for the info though. I thought that compliance may have been the issue. If I find out that it isn't a compatibility issue I'll let you know.

I have now switched ot the modem five times with five different modems. Not a single one of them worked! It is an older board. It's an old ASUS that has a 533 Mhz CPU. Could that have anything to do with it? Any ideas? I tried looking up a list of XP compliant modems on the Microsoft HCL but it wasn't much help. If anybody has any ideas, I am open to anything. Thanks!
