Indeed you're right, this should be fixed. I'll try to debug my brl_open() and find out where it bugs. 
But anyway, I continue thinking about the fact that the driver should not close the link: In the EuroBraille displays, when the link is closed, a message "Link Dead" is printed on the braille display. This would be a problem if the user thinks that BRLTTY died and try to launch a second one (which means concurrent access to the serial port). I prefer the "Screen not in text mode" message, which I can't see anymore because it is replaced by the "link dead" one.

I'll keep you informed with my brk_open() investigations.
