Paul, Scott et al.,
Because I do quite a lot of serial from my Macs I consider myself
lucky that so far I don't seem to be affected by this subtile bug.
However, it could really lead to hard to track down effects with
serial communication and of course it should be reported firmly and
right away. I really hope NI developers in charge will straight it
out soon.
Thank you guys for spotting this bug!
Happy wireworks
