With the exception of not using warnings and strict, it SEEMS like you are doing it right. Sadly, I have a DSL modem now, and will have to test this later on a different machine. BUT, there are some things you can try.

If you look at the dial method in Modem.pm, it incorporates a timeout, and it probably is "blocking the gui" while it dials and waits for the timeout to connect. So during that time Tk is blocked. A possible solution, is not to use the dial method, and manually send out each digit at a time, and in-between let Tk do a 1-loop, to see if you hit the cancel button. Something like: 


use Tk::Event qw(DONT_WAIT);

sub push_button { 
       $txt -> insert ('end',"Dialing $number\n");
     
      #$modem->dial($number);
        my (@n) = $number =~ /\d/g;
        
        foreach my $d (@n){
           
         $modem->atsend(  'ATDT'. $d . Device::Modem::CR );
           DoOneEvent(DONT_WAIT);    
        }

}
