History
2006 February, A-Shell 4.9.950: PUTBYT now supports channel 0 to output to the terminal device. This can be useful (mainly under Unix) if you need to output raw binary data to the terminal and want to be sure there is no filtering and do not want it to corrupt the screen map. Otherwise, typically you get Tab expansion (unless OPTIONS=RAWTABS), and CR is always prepended to line LF characters.
