Dear Monks, This is my first program using sockets, so I might be doing something foolish - if so excuse me. I'm trying to write a simple client which connects to a server, receives data, processes it, and prints it to the screen. The problem I am having is that the program hangs for 20-30 seconds, prints out a spurt of data, and does this several times before the connection times out on the server. Here's the code: 
{

    $sock = new IO::Socket::INET ( PeerAddr => $host,
                                   PeerPort => $port,
                                   Proto => 'tcp',
                                   Reuse => 1
                                 );
    $sock->autoflush(1);

   print $sock "log in information";

   my $read_set = new IO::Select($sock);

   my $incoming_server_data = "";

   while (1) {
       my @ready = $read_set->can_read(.5);
       foreach my $rh (@ready) {
           my $line = <$rh>;
           $incoming_server_data .= $line;
           parse(\$incoming_server_data);
       }
   }

}

The printing is done inside the parse function. I thought that might be the problem, but replacing the call to parse() with a simple print "$line\n"; did not change the problem.
Update
Answered! Changing my $line = <$rh>; to sysread $rh, my $line, 1024;, per etcshadow's suggestion, did the trick. Thanks!
