Bob, it's best to do output buffered, and one-key-at-a-time (no ENTER) input as
unbuffered.  You can get the corresponding "raw" (Unix-ese) channel number as
"stdin->_fileno" or something close -- look in stdio.h to be sure. Just be sure
that whenever you do unbufeered I/O on the same path as buffered, always
fflush() the path first.

Also you can set buffered output so it WILL NOT turn CRs and LFs bytes into
CR-LF pairs.  Do stdout->_flag |= _RBF.

Ask for more details if needed.  Don't use setbuf(). But use fprintf(stderr,
...) if you want instant output quick.
