Take a look at the tdma module. There is already a rtdm_event_t being used to signal the beginning of a cycle (i.e. the reception of a sync frame). You may add another rtdm_event_t to the tdma discipline structure, signal the event after transmitting a frame in some slot, and extend tdma_dev.c appropriately so that RTMAC_WAIT_ON_XMIT lets the caller block on this new event. Patches are welcome! And if you don't understand any details of the existing code, feel free to ask. Jan
