I assume you are saying that you are getting a "No Carrier" message back.
If that is the case, does your ISP support 14.4?  

If it is an issue where you are not getting the message but some cryptic code,
you should look for "verbose result codes"  ([Xnn] or [Vn]).

So you did a

P.S.
at &v    should show you your modem settings.
