My current theory is that with RTNET you need a Connect() to do a Send(). Connect() only works if a socket is not in listen().
Not sure what happens yet if I change the send() to a sentto() if the first example On Xenomai , Sent() does not error. it just blocks. On RTAI, it produces an "oops". I have extended the pools via RTNET_RTIOC_EXTPOOL to both 30 and 1024 with no effect on above.
