Tonight, noticed long periods of wind outages at S8.  The rserial output show that these period have data values of 999.99 with an error code=04 (the manual says that the value of this code provides "no useful information to the user"!).  However, I also see reasonable data interspersed with the bad periods.  I suspect a bird is roosting in the array (despite Dan's heroic effort at making bird spikes) and that this problem will go away.  Just to do something, I ddn/dup and eio 6 0/1, to no effect.
