@topic 4.5 Port Overview |
|
|
|
|
This section describes the interfaces defined in <f Port\.h>.
|
|
|
|
The sample does not use this interface, but it is anticipated that it would
|
|
be used to maintain information associated with each physical ISDN line.
|
|
Assuming that each card may have multiple ISDN lines plugged into it.
