The point was not to figure out how to do it.. I know how to do it.. Here is my 'test' code.

#!/usr/bin/perl
use IO::Socket;

$sock = IO::Socket::INET->new( PeerAddr => '192.168.0.4',
                               PeerPort => 4000,
                               Proto    => 'tcp'
                              );

$flags = fcntl($sock, F_GETFL, 0)
        or die "Can't get flags for socket: $!\n";
fcntl($sock, F_SETFL, $flags | O_NONBLOCK)
        or die "Can't make socket nonblocking: $!\n";

print $sock "logn 0607daimuntemp123\n";

while(1) {
  sleep 1;
  $str = <$sock>;
  chomp $str;

  print $str . "\n";

  if( $str =~ /^$/ ) {
    print "null\n";
  }
}

When run, it results in this error:
fcntl is not implemented at sam.pl line 10.
