@topic 4.2 Card Overview |
|
|
|
|
This section describes the interfaces defined in <f Card\.h>.
|
|
|
|
This module isolates most the vendor specific hardware access interfaces.
|
|
It will require signficant changes to accomodate your hardware device.
|
|
You should try to isolate your changes to the <t CARD_OBJECT> rather then
|
|
the <t MINIPORT_ADAPTER_OBJECT>. This will make it eaiser to reuse the
|
|
upper portions of the driver should your hardware change in the future.
|
|
|
|
The driver assumes one <t CARD_OBJECT> per physical ISDN card. The card
|
|
object is always available via the <t MINIPORT_ADAPTER_OBJECT> which is
|
|
available in nearly every interface the driver supports. Each
|
|
<t CARD_OBJECT> contains one or more <t PORT_OBJECT>s depending on how
|
|
many physical ISDN lines your card supports.
|
|
|
|
You should add all your physical card related data to the <t CARD_OBJECT>.
|
|
You can also add any card related registry parameters to this structure,
|
|
and the <f g_CardParameters> table.
