Is this an internal or external modem?

So you get nothing when you type 'AT' followed by enter with nothing else?

And this makes me ask my first question.  Is this internal or external?

These should at least get the result codes you need.  Maybe try an at&f1
which is Load Factory 1, HW FC and see if that gets the OK working.  The 
only thing I could do to mine to turn of the OK is Q1.
