Tcl automatically detects whether <tt>stdin</tt> is coming from a terminal (or a socket) and sets up the channel to have the correct type. One of the configuration options of a terminal channel is <tt>-mode</tt> (used to configure baud rates on a real serial terminal) so we simply detect whether the option is present.
