141 The character-mode devices for the
143 driver should only be used for accessing the audio features of the

146 The current version of the driver uses neither the DMA or IRQ
147 features of the interface board, although it has an interrupt handler
148 for any IRQ requests that are generated.
149 Until the DMA features are
