I would create a master status vector for the 2-way devices. Usually, it is possible to determine why a synchronous or asynchronous status has been returned and the appropriate vector component can be updated. The vector components would always contain the latest available data that program elements can interrogate as needed. While program elements would not need to request, then wait for data, no scheme can be absolutely bomb proof because an important reply could have been flushed from the buffer.
