USR 5610-B modem problem: becomes inactive erratically

USR 5610-B modem problem: becomes inactive erratically

USR 5610-B modem problem: becomes inactive erratically

Not so long ago I got a used computer having an internal, US Robotics, 56K, PCI "Performance Pro" modem (model 5610-02 aka 5610-B). In this computer I installed 2 OSs on the single HDD: Win98 1st Edition and Linux. I had the same modem problem with both OSs. The problem is that I can connect to the Net but the modem becomes inactive unpredictably. It can work fine for a minute or two or for a few hours but then suddenly becomes inactive-- I don't know if something I do triggers this inactivity or if it just happens. Nothing freezes up and no crashes occur but I can't send or receive email nor go to any website. When this happens with Win98, my Win98 Net connection icon says the connection is there. Also, when this happens, I found that if I pick up the nearby phone handset (which is on the same phone line as the modem) I hear modem connection sounds. I usually listen to one or two sets of these modem connection sounds, put down the phone handset, and find that the modem is OK again: I can use email and go to any website. [Remember, this same problem occurs *in the same computer* when I used the Linux OS with this modem.]

I recently took out this modem and put it in another computer which runs Win98 1st Edition as OS. The same problem occurs.

I contacted US Robotics about this but all they tell me to do is update my BIOS. I did that but the problem has not gone away.

The init string I have for this modem is simply AT&F.

Does anyone here know what could be wrong and how this is fixed? [I believe I have the latest drivers for this USR modem.] Is there some unusual or common setting that has to be changed or set somewhere? [I have this modem now only for a Win98 1st Edition computer.] I figure that since I had this same exact problem with two different operating systems (when I had these two OSs in the computer into which this modem was installed), the problem must be with the modem and not something else.
