|
* 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.
