- *     DATA STRUCTURE: DMA STREAMS - DMA streams are objects of the class EDI-STREAM-DMA used to pass data between a buffer of
- * memory and the computer's DMA hardware.  It is the responsibility of the object to allocate memory for its stream memory buffer
- * which can be used with DMA hardware and to program the DMA hardware for transmissions.  DMA streams can be bidirectional if the
- * correct DMA mode is used. */
