Jack switching to get a dial tone

U.S. Robotics 56K Software Modem on Windows 2000 Professional

A while back I tried to connect to the internet and I received a "no dial tone" error. I had just been on earlier that evening and everything worked fine. Thinking I may have put the phone line into the wrong jack on the modem, I switched the line to the unoccupied jack. My modem found a dial tone. Later when I tried to connect again it didn't find a dial tone. I switched the line back to the other jack and it found a dial tone again. So now every time I wanted to connect I had to switch the line to the unoccupied jack. I quickly became tired of this so I completely reformatted and reinstalled everything on my computer. The modem worked fine again, but soon after it started to do the same thing again. Based on this I don't think it's any kind of modem damage, but something to do with software, maybe a virus or something. This is all really bizarre to me and I was wondering if anyone had any thoughts on why it would be doing this, and hopefully if anyone knows how I would fix this problem.

Thanks,

Brian

1) Software modems are a bit finicky; real modems are better, external ones usually gives the least trouble.

Having said that (displaying my hobby-horse) I have to ask if your phone lines work OK otherwise?

I was lead to think about the modem not "hanging up" properly (which would cause the exchange to put the line to "sleep", after a period of time, until connection was broken and re-established). This could be caused by hardware (cables, connectors, modem circuitry) or software (drivers).

So, after disconnecting your modem through the program, do your phones work OK on this line?

Yes, my phones work OK after I disconnect through the program, but I think you're right about the modem not hanging up properly. I've had quite a few people tell me that software modems are kinda shaky at best, so I think you're right in that respect. I'm going to install a nice hardware modem and see what happens.

I think you awarded me the points prematurely, as my suggestion didn't solve your problem. Not that I disagree with your proposed course of action, but you might have received better advice from someone else here, if you had left the Q open. I think the points should be refunded, and I will post an entry to that effect in the Communit Support area.
