Playing with some ioctl but not having any success. This is supposed to turn off the CAPS-LOCK LED. I'm starting to think that maybe ioctl is out of favor and therefore not well supported. I ran h2ph -r -l -h . in /usr/include. I even came across something called h2pl but it appears to be vestigial. 
require 'sys/ioctl.ph';
sysopen( FD, "/dev/console", 1 ) or die "Unable to open /dev/console";
select(FD);$|++;
my $KDSETLED = 0x4B32;
my $stat = ioctl(FD, $KDSETLED, 0x0) || -1;
close(FD);

print STDOUT "status = $stat\n";

In reply to ioctl - does it actually work? replaced or preferred by something else? by Jack B. Nymbol
