Having 0x10 set causes arduino to reset when serial message is sent

Having 0x10 set causes arduino to reset when serial message is sent when connecting via windows. I modified my copy of the library to remove this line.

jeez I wasted so much time yesterday trying to figure out why my Arduino was resetting when I sent data using this library. Thanks for finding out wha the problem is.
Happens in OS X too. I would not say this is a library problem specifically but it would be great to make this behaviour configurable.
Agreed - Probably shouldn't have submitted this as a PR per se, but having it open - I think - is helpful to others who may experience the same issue.
In this instance I made the quick and dirty change that suited my usecase, but glad it helped you as well @donotnoot !
