Boost.Asio supports serial ports as well.

There are examples of client / server applications, and although based
on sockets, with appropriate modifications could run over, say, serial
ports.

I use Boost.Asio not only for sockets, serial ports, and files, but also
to implement asynchronous message passing between threads. This involves
using io_service.post() to post functor objects to the thread. I usually
use the "active object" kind of idiom in this case.
Anyway, my point is that I believe Boost.Asio can be used for the kinds
of things that you describe.
