Members

usOpenErrorCode

Indicates the result of the open adapter testing.

usOpenOptions

Specifies the open options for the adapter. This member is a 16-bit value. Setting the various bits enables different options, as described in the following table:

Bit	Description
15	The adapter will not attach itself to the network. Instead, it causes all transmitted user data to be wrapped as received data.
14	Disables hard errors.
13	Disables soft errors.
12	Passes, as direct interface data, all adapter-class MAC frames that are received but not supported by the adapter. Otherwise, these frames are ignored.
11	Passes, as direct interface data, all attention MAC frames that are not the same as the last attention MAC frame received. Otherwise, these frames are ignored.
10	Reserved; should be 0.
9	Reserved; should be 0.
8	Participates in monitor contention. Otherwise, this adapter does not participate.
7	Passes, as direct interface data, the first beacon MAC frame and all subsequent beacon MAC frames that have a change in the source address or the beacon type.
6	Reserved; should be 0.
5	Prevents the adapter from becoming a monitor during the open process. This bit is implemented only in 16/4 adapters.
4	Selects no early token releases for an adapter operating at 16 Mbps. Otherwise, use the early token release.
3	Reserved; should be 0.
2	Reserved; should be 0.
1	Reserved; should be 0.
0	Reserved; should be 0.

auchNodeAddress

Specifies the LAN address of the adapter.

auchGroupAddress

Specifies the group address for which the adapter will receive messages. If the value is zero, no group address is set.

auchFunctionalAddress

Specifies the functional address for which the adapter will receive messages. The most significant bit and the least significant bit are ignored by the adapter. If the value is zero, no functional address is set.

usReserved1

Reserved.

usReserved2

Reserved.

usMaxFrameSize

The maximum frame size defined in NDIS.

usReserved3

Reserved.

usBringUps

Indicates the result of adapter bring-up testing for IBM Token-Ring network adapters. This member is not used on the PC Network or on Ethernet.

InitWarnings

Indicates that a nonfatal error occurred during initialization of the protocol drivers. This member can be one of the following values.

Value	Meaning
0	No errors detected during configuration parameter processing.
1	No configuration parameters found.
2	Errors detected during configuration parameter processing; default values were used.

usReserved4

Reserved.
