I went through and disabled everything in xeno except
CONFIG_XENO_OPT_PERVASIVE, did not work. Take that option out and it works.

Take that option out at anytime it works.

My program basic writes a few characters a serial port and then reads them
back in from the same port. I have a loop back cable connected to the port.

It writes the data but waits forever to read them back in

>From my tests, it appears that the termois tcsetaddr settings is not getting
set when I call it when this option is on.
