How I do broadcast in Perl with sockets?

I have the following code:

sub sendbroadcast {
 my $msg0 = $_[0] || '';
 my $port = $_[1] || '';   
 my ($iaddr, $proto, $thataddr, $sockaddr, $msg);   
 return 'Error. Port empyt' unless ($port);
 #Conf Conn 
 # resolve protocol, port number
 $remhost= '192.168.0.255';
 $iaddr= inet_aton($remhost) or $msg= "No host in  sendbroadcast: $! -
+ $GREMOTE";
 return "$msg - $remhost:$port" if ($msg);      
 $sockaddr=sockaddr_in($port, $iaddr);
 $proto = getprotobyname('tcp') || 6;
 socket(BRFD, PF_INET, SOCK_STREAM, $proto) or $msg= "Socket in sendbr
+oadcast: $!";
 return "$msg - $remhost:$port" if ($msg);   
 connect(BRFD, $sockaddr)  or $msg= "connect in sendbroadcast: $!";
 return "$msg - $remhost:$port" if ($msg);
 $msg = $msg0 . '#' x (1024 - length($msg0)); 
 syswrite BRFD, $msg, 1024;   
 close (BRFD);      
 return "Sent message";
}

but when executing it prints it: the network is inaccessible
