Thank you. But it does not work. Nor work similar other tricks like:

$Serial->baudrate(int($baud_rate))
$Serial->baudrate("$baud_rate")
$Serial->baudrate(eval{$baud_rate})

[download]

The following seems to work (in the sense that it does not produces an error message), but the serial stream does not have the baudrate it is supposed to have

$Serial->{"_L_BAUD"}{$baud_rate} = $baud_rate;
$Serial->baudrate($baud_rate);

[download]

I don't know what it may be

    It was my fault. The code was in a subroutine where $baud_rate was passed by reference and used as if it were passed by value. After correcting the mistake the following construct worked perfectly: 
     
$Serial->{"_L_BAUD"}{$baud_rate} = $baud_rate;
$Serial->baudrate($baud_rate);
