 * You can use anything that you can write a console interface for:

 *	send token + "1\n" for on
 *	send token + "0\n" for off,
 *	send token + "#\n" for which (optional)
 *	send token + any-other-character + "\n" for your own extensions
 * Basically we tell the client to attach to that console port and send
 * the "token" + the command characters until it sees ".".  Then return to
 * us.  Easy.  A sample C program to put on a Virtual console would be
 * simple (to interface to more complex power controllers).
 * The power controller can be password protected separately from the
 * console line... of course.	-- ksb

 * This extends the configuration line by two fields [:token:line@sever]
