Well, it looks as if you have forgotten to set the serial port
settings for the modem. You have to find out which IRQ and IO address
the modem likes (or if it's SearchnDestroy, sorry PnP, you need to
configure the IO and IRQ using pnptools). Then, you can use setserial to
set the port up to what the modem is set up.

Is that in minicom or similar? What should happen is that
whenever you boot minicom, a couple of LEDs in the modem should light up
(at least, my V21 modem does :D). And then you can tell minicom the port
you're using (/dev/ttySX), and AT should reply fast enough. If takes a
while to reply, prolly wrong IRQ.

Nothing wrong in using POTS modems. They are cheap, easy and
nice. I'm getting fiber into my house (ha!)

The problaby windows reset the PnP settings of the modem, or
similar... Hard to tell from the distance (I find modems to be an
iterative process, that follows a random walk kind of pattern).
