Does the laptop know it has a modem attached? Check under the control panel and see the modem icon, use the diags provided by trying "more info" it should talk to the modem before any dail-up attempts. If it fails or errors, then I suspect you need the modem driver in order to fully install it and/or select a COM port so it can use besides any the laptop provides as that may cause a conflict. To get the driver if none, goto the modem makers and for your model get the driver and OS required. Hopefully, that should resolve it. Get back with results.
