* isic - I4B Siemens ISDN Chipset Driver for Creatix/Teles PnP
* ============================================================
*
* $Id: i4b_ctx_s0P.c,v 1.4 2000/08/22 11:30:04 hm Exp $
*
* $FreeBSD$
*
* last edit-date: [Fri Oct 13 15:59:45 2000]
*
* Note: this driver works for the Creatix ISDN S0-16 P+P and
* for the Teles S0/16.3 PnP card. Although they are not
* the same hardware and don't share the same PnP config
* information, once the base addresses are set, the
* offsets are same and therefore they can use the same
* driver.
