Here's some client code for a slower responding socket server, or when all the data doesn't show up at once, due to other issues. It sends a chunk, and waits for a response, up to N loops. Small sleeps might be safer than just looping, but hey, everyone works differently. You also could add checks for some termination sequence, or checks for the chunk meeting a fixed size requirement.

my $indata;
my $remote = IO::Socket::INET->new(
  Proto    => "tcp",
  PeerAddr =>'127.0.0.1' ,
  PeerPort => $self->{'30000'},
);
if( defined($remote) ) {
  my $readsize;
  print $remote  $bigdata;          
  my $done = 0;
  my $zreads =0;
  while (! $done) {
    my $tempdata="";
    $tempdata = <$remote>;
    $readsize = length $tempdata;
    $zreads++ if ($readsize == 0);
    $done = 1 if ($zreads > 30);
    $in_data = $in_data . $tempdata;
    $done = 1 if ($tempdata eq "\n");
  }
  close $remote;
