//
// If an io.ReadWriteCloser is not supplied, the Adaptor will open a connection
// to a serial port with a baude rate of 57600. If an io.ReadWriteCloser
// is supplied, then the Adaptor will use the provided io.ReadWriteCloser and use the
// string port as a label to be displayed in the log and api.
