Write your reply.

assistant: Bill,
    I'm not sure if you got my last response to you, but here it is
again:
Bill,
    What is the model number of the ACCURA 28.8 that you have?  If you
could, please issue an ATi3 to the modem and let us know what it returns
so that we will be able to tell exactly what version of the modem you
have.  Is the modem external or internal?  If internal, what com port is
the modem configured for and what com ports do you have on the system?
Please let us know what you find.
As for our online support, we can be reached via any of the following
