Yes, this problem is exactly why I prefer external modems. I power
them through a clockwork switch which cuts the power for 15mins at
four in the morning.
In my case, it's not windows that causes the problem (I don't use it),
but just being left on 24/7 for more than a few days. The symptoms are
the same - everything (AT, ATDT, etc.) gets to the modem and is
reflected back, but the modem never goes off-hook.
In some cases, the modem has just answered an incoming call but fails
to call back, other times I just decide I want to dial out and it
won't. And, yes, it's common to all my USR modems (3 x 33k, 1 x 56k).
Cheers,
