             _start => sub {
               ReadMode "ultra-raw";
               $_[HEAP]{io} = POE::Wheel::ReadWrite->new(

               );
             },
             got_some_data => sub {
               $_[HEAP]{io}->put("<$_[ARG0]>");
               delete $_[HEAP]{io} if $_[ARG0] eq "\cC";
