John, thanks. I bought that computer in Oct 98, so it was just a matter of time before something went that I didn't feel like fixing. The modem, by the way, was the newest thing on there. It doesn't have an ethernet jack, and the same line that didn't work in that one is working fine in the external modem I'm now using. Line OK. The modem tries to dial, and says there's no dial tone, so it's the connection between the line and the modem. If the line is OK, and the modem's mostly OK, and I don't have an ethernet jack, there's one other thing it might be that's related to stupidity.

Yep. I just checked, and in the flurry of plugging and unplugging yesterday resulted in the phone 'out' line being still stuck in the phone 'in' jack. Phone still worked, but the phone likely doesn't care what it's stuck in as long as there's a connetion. It's amazing how one's IQ can be improved by walking away for a while. (Then coming back and doing the stuff you thought only 'stupid' people should try.) I'll see if fixing this works when I get off line.
