Hi Andrei!
Thanks for the detailed description, we should put it on the wiki.

So, how does send_timeout work in async mode? The write is non-blocking,
that means the kernel accepts the data and the write/send function
returns immediately. Now, the kernel tries to send the data for
send_timeout seconds. If this fails, what happens now? Is there a
callback from kernel to ser or does ser somehow poll if the sending was
successful?
