If the installation goes smoothly, but you get a 'No Dialtone' response from the modem,
you might be able to fix it by changing the BIOS Plug-n-Play settings:
select "non-PNP OS" or "Other OS" rather than the (probable default) "PNP OS" or "Windows."

Check also if the modem has a nonzero IRQ value by issuing the command:
	 lspci -vv
and looking for your modem card in the output.
On some Systems, this is affected by the PNP choices.


For possible updates on the following, check:

       4.NO DIALTONE message: please check your IRQ's, wrong, or conflicting. Use setserial -agv /dev/modem
         and cat /proc/interrupts, the latter should not show the IRQ reported by the former. 
       5.Still NO DIALTONE: edit /etc/wvdial.conf. By default it shows place holders or text for 3 Init strings (you
         can add more up to 7). Try to add ATH1 as last command in last non empty string. Return to step
         vwdial. 
       6.Still NO DIALTONE: add AT+GCI=xx in the Init string, where xx is your HEXADECIMAL country code
         found here (in spite of what it says, use the AT+GCI syntax for Lucent modems). Your modem may be
         trying to listen to the wrong frequency. 
       7.Still NO DIALTONE: find a cable known to work with an other modem and your phone line outlet, and
         try again (your cable may fail to match the phone company wiring - especially in Switzerland for example
         if the modem comes from elsewhere. Check that you have the right adaptor).
