I don't have a way to pass the asio::yield_context through the 3rd party library to the callback and invoke async_write_some() with it, but thought write_some() in non-blocking mode would work. WebTo write a single data buffer use the buffer function as follows: serial_port.async_write_some (boost::asio::buffer (data, size), handler); See the buffer documentation for information on writing multiple buffers in one go, and how to use it with arrays, boost::array or std::vector.
