 * $Log: isdn_ioctl.h,v $
 * Revision 1.3  1995/11/16 10:44:48  bde
 * Completed function declarations.
 *
 * Added prototypes.
 *
 * Revision 1.2  1995/03/28  07:54:45  bde
 * Add and move declarations to fix all of the warnings from `gcc -Wimplicit'
 * (except in netccitt, netiso and netns) that I didn't notice when I fixed
 * "all" such warnings before.
 *
 * Revision 1.1  1995/02/14  15:00:35  jkh
 * An ISDN driver that supports the EDSS1 and the 1TR6 ISDN interfaces.
 * EDSS1 is the "Euro-ISDN", 1TR6 is the soon obsolete german ISDN Interface.
 * Obtained from: Dietmar Friede <dfriede@drnhh.neuhaus.de> and
 * 	Juergen Krause <jkr@saarlink.de>
 *
 * This is only one part - the rest to follow in a couple of hours.
 * This part is a benign import, since it doesn't affect anything else.
