You CAN receive ascii events in a TEXTSW.  What you have to do is register
an "interposer" function with the Notifier.  This will cause all events
directed towards your TEXTSW to be routed through your interposer function
before going to the Base event handler.

After you create your text subwindow, register your interposer function
using the function "notify_interpose_event_func".

For example:
	notify_interpose_event_func(my_textsw, My_Interposer, NOTIFY_SAFE);

"My_Interposer" might look something like this:

	static void
	My_Interposer(frame, event, arg, type)
	Frame   frame;
	Event *event;
	Notify_arg arg;
	Notify_event_type type;
	{
		.
		.
		.
		if (event_is_ascii(event))                  
		{
			ch = (char) event_id(event);
			.
			. 
			. 
		}
	}
