-/**
- * Terminal that is used for unix platforms. Terminal initialization
- * is handled by issuing the <em>stty</em> command against the
- * <em>/dev/tty</em> file to disable character echoing and enable
- * character input. All known unix systems (including
- * Linux and Macintosh OS X) support the <em>stty</em>), so this
- * implementation should work for an reasonable POSIX system.
