Hi!
It's a framing error!
Look here http://forums.ni.com/ni/board/message?board.id=170&message.id=163477&view=by_date_ascending&page=1 to find some infos on why framing errors occurs!
The simplest way is to have not correct settings for the port, but I think it's not the case, because HT works....
Anyway, Hyper terminal doesn't show framing errors occuring! Don't trust HT too much!
Please, let me know how you will solve!
