I need to simulate the behavior of a serial port using Sun Ada.  The problem I
am having is that the functions in text_io block until a <CR> is entered.  I 
need to return each character as it is typed and some status code if there are
no characters available.  Is there a way to do this in Ada?



Thanks ,
