I think the comments in the lint file describe this. The flags (if defined) are used to define the read dma channel for the gus/gus-max card when in full duplex mode. If the read dma channel is not defined, then the gus card runs in the standard 1/2 duplex mode. If the flags are defined and the drq (write dma channel) is different than the flags (read dma channel), then the gus card runs in full duplex mode. -Jim
