Ran into the same problem. Did not investigate it to the core; however, I was
using a Cardinal modem. I simply went back to my US Robotics. Since, I have not
had time to pursue the problem, I am *assuming* that the message arises from
the "intelligent" firmware on the Cardinal. But, this is only a wild guess. 
And, probably, I'm quite off base.
