Answer 1

In addition to the baud rate, you may also need to set other options like: character_size, flow_control, parity and stop_bits. To write your data to the serial port you can do the following:

boost::asio::write(port, boost::asio::buffer(commands, 4));

The libraries acceptance of buffer types is very flexible and you may want to read further on that topic here: Buffers.
