I think your code never enters this loop 
 while(<$client>)
     { print $_;
       print $client "Username $user Pass $pass";}

I think what you need is more like this: 
  print $client "Username $user Pass $pass";
  while(<$client>)
  {
    print $_;
    <STDIN>; #read input from user (changes $_!)
    print $client $_;
  }

For the other part, I don't see why this (code below) would not work. again. if the variables contain what they should. Always check your input! 
  $host = $ARGV[2]; #or whatever it is in your ARGV
  $port = $ARGV[4];

  my $client = IO::Socket::INET->new(
        PeerAddr => $host,
        PeerPort => $port,
