Now the reconnection does not succeed either and after some tries I obtain an invalid file handle error.
I guess I am missing some fundamental thing with asio ...

Any further comment?
I think you should simplify your close semantics, passing an error code to your do_close() method is making it do more work than necessary. I don't understand the recreation of the serial_port object although I have not used the serial_port functionality myself. Also the close() method posts a do_close() call with a default constructed error object which is not handled correctly. I'm not sure why you need to use a loop in the main routine, if you want a server then use pending async calls to keep the io_service alive, if you want a client then perhaps errors should simply cause graceful termination. ... snip ...
