If you are using Windows, you can use Win32Readch, function
readch_block() like so:
use strict;
use warnings;
use Win32::Readch qw(readch_block);
print "Press a single keystroke:\n";
my $ch = readch_block;
if (ord($ch) == 8) {
print "Backspace\n";
}
else {
print "Character '".ord($ch)."' has been pressed\n\n";
}
