29 * ============================================================
30 * last edit-date: [Wed Jan 24 09:07:22 2001]
32 * Note: this driver works for the Creatix ISDN S0-16 P+P and
33 * for the Teles S0/16.3 PnP card. Although they are not
34 * the same hardware and don't share the same PnP config
35 * information, once the base addresses are set, the
36 * offsets are same and therefore they can use the same
