In general, unbuffered I/O DOES change the configuration of the I/O 
interface.  This is especially true of the UNIX and MPX-32 operating 
systems.  As a result, you can't mix your own unbuffered I/O with 
buffered I/O via TEXT_IO.  Furthermore, you have to be sure to restore 
the original I/O parameters before you end your program, or else your 
responses to the command line won't echo any more!  You have to know what 
you are doing if you are going to do unbuffered I/O.
