I guess the problem is you are calling rtl_wait() in the FIFO handler. FIFO
handler is not run in a periodic task context.
case BIT_PATTERN :
fun(msg.bits);
rtl_schedule();
Also rtl_schedule() seems not to be documented.
As I understand you want to generate pulses of a given length. It would be
better to use single-shot mode. Now the "fun" function is called many times
periodically without any change of the byte written to the paralel port.
I think I will be working on a similar problem soon.
