OID_WW_CDPD_HEADER_COMPRESSION
The OID_WW_CDPD_HEADER_COMPRESSION OID requests the miniport driver either to return the header compression scheme that is currently in use or to set the value that is initially used in negotiating the header compression scheme.
In either case, one of the following designates the header compression scheme:
| Value | Meaning |
|---|---|
0 |
No header compression. |
1 |
Always compress headers. |
2 |
Compress headers if the Mobile Data Intermediate System sends a compressed header. |
-1 |
Unknown. If this value is specified for a set, the miniport driver returns NDIS_STATUS_INVALID_DATA. |
Indications are irrelevant for this OID.
Note This OID is not available for use beginning with Windows Vista.
