Dear Boost.Asio developers,

I wanted to know if there was any interest for a
mockup_serial_port_service, so that one might write cross platform
unit-tests of code based on serial_port.

I implemented this mockup this summer for a project where the best way
to unit test some modules was to act as another peer on a serial port
and needed to be doable on any platform supported by asio::serial_port.

I find it quite useful, because there

  - is no need to use separate tools like socat on linux or install
virtual COM ports applications on windows. Which ease the setup of the
test environment
  - the fake serial port doesn't pollute the system where the test is run
  - many test cases can be run in parallel, as there is no native
ressources involved.

One might use it as this  :

>   using namespace boost::asio;
> 
>   boost::thread simulate_writing_device([](){
>     io_service ios;
>     basic_serial_port<mockup_serial_port_service> port{ios, "my_fake_serial_port"};
> 
>     const std::string message = "Hello";
> 
>     for (;;) {
>      boost::asio::write(port, buffer(message.data(), message.size()));
>      boost::this_thread::sleep_for(boost::chrono::seconds(1));
>     }
> 
>   });
> 
>   boost::thread simulate_reading_device([](){
>     io_service ios;
>     basic_serial_port<mockup_serial_port_service> port{ios, "my_fake_serial_port"};
> 
>     for (;;) {
>       char message[5];
>       boost::asio::read(port, buffer(message, 5));
>       std::cout << "received : " << std::string(message, 5) << std::endl;
>     }
> 
>   });

A short documentation is available here : http://goo.gl/24JnUg

And the implementation is on github in a holdall library for the moment
:  https://goo.gl/E7KGdn

It's a library whose goal is to shrink over the time as they get merged
in upstreams project.

Hopefully there is interest for this mockup_serial_port, and if so I'll
cleanup the code some more and make a pull-request to Boost.Asio.

Cheers from Berlin where meetingcpp already ended :'-(
