New Haven,CT Lines: 15 I defined the constant DMFDMA to enable DMA output from the DMF32 but there are two undefined variables in the dmfstart() routine when the DMA mode is enabled. This makes me think that the code has never been "tested". We used to run the 4.1 dmf driver in DMA mode, as I recall. Has anyone done this ? Is anyone out there running 4.2 with the DMF in DMA mode ? We have a 750 with 24 terminal lines on the DMF and our system CPU % has been quite high lately, making me think that running our terminals using DMA output might help.
