While i haven't a comment on the socket side of your code, you may want to reverse the logic of your $connected flag. Intuitively, if I see a flag such as "$connected", the assumption is that a true value would mean we are conencted.

Then you can say something like: 

if ( $connected) {
    print " Port $port is up.\n";
}
else {
    print " Port $port is down.\n";
}

That also means you will have to reverse the logic in your "or" modifier, but your program will more intuitive and easier to maintain.
