Another option is to use:
select( undef, undef, undef, x )

where x can be fractions of a second:
select( undef, undef, undef, 0.26 )
select( undef, undef, undef, 0.76 )
select( undef, undef, undef, 5.49 )

How odd.  You could try sleeping between prints:

    foreach my $c (split //, $string) {
        print SERIAL $c;
        sleep(1);
    }

A second is quite a bit of time to wait in a program, so you may want to
use
Time::HiRes and usleep for a few milliseconds.
