I'm not sure what you are asking, and you show no code, but I think you should google for "perl select client" and look at the examples. I would think from your description, is that you want a client to connect to multiple servers, and read write to them? The problem it seems to me, is when a message comes in, how would you know which of multiple servers to write to? You will have to keep a hash of the sockets and see who is sending, then reply to that socket. Usually a client is forked to make it bi-directional, see UDP bidirectional client

Things get complicated fast, if you want a bidirectional client that connects to multiple servers simultaneously. See Simple bi-directional forking commandline client for a single connect client. You could do probably it with select, but it will involve a complex while loop check like this: 

# very crude pseudocode
my $select = IO::Select->new($server1);
$select->add($server2);
$select->add(/*STDIN);  #for sending
# etc etc

my @ready;

while(@ready = $select->can_read) {
   my $socket;
   for $socket (@ready) {
       # see if you can read a socket
        .....
        .....
    }

#see if $select handle is STDIN, if so, send it to all in @ready
}

# do socket close error checking here

The complexity will get so great, that you are better off using an eventloop system to watch your sockets, like POE or Tk or Gtk2. POE may have something already in it's cookbook, google for it. Look at the Tk client in Simple threaded chat server , it uses fileevent (similar to select) and it would be easy to extend to multiple server connections.
