Or where do you have the information about `#define's from. Is the MUX_LINE_OFFSET (= 0x80) the key point. I have tried to access the board at membase + MUX_OFFSET + line * MUX_LINE_OFFSET, but the first write access to /dev/ttyB1 results in a hang up (completely, even no network interrupts were processed !). Operates the MUX driver in polling mode ? Not in IRQ mode ?
