GPS Intermediate Driver Poll Registry Settings

For more information about how to use these registry settings and IOCTL, see Implementing GPS Intermediate Driver Hardware IOCTLs.
The GPS Intermediate Driver will use the settings in this topic when the InterfaceType registry entry is "Poll". For more information about the InterfaceType registry entry, see GPS Intermediate Driver Input Source Registry Settings.
Like the InterfaceType registry entry, these entries exist in a key named for the specific input source, beneath the HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers key. For example, an input source that uses GPS hardware directly might have registry settings at the HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers\AcmeDirectGPSHardware key.
Note
On some target devices, the root GPS Intermediate Driver registry key, and all subkeys, are protected. On these target devices, untrusted applications can read but cannot write GPS Intermediate Driver settings.
The following table shows the registry entries that specify direct GPS hardware connection information.
| Value : type | Description |
|---|---|
PollInterval : REG_DWORD |
Default setting is 1000 milliseconds. Minimum amount of time, in milliseconds, that the GPS Intermediate Driver waits between calls it makes that use the IOCTL_GPS_DRIVER_GET_LOCATION_V1 and IOCTL_GPS_DRIVER_GET_LOCATION_V2 IOCTLs. |
Version : REG_DWORD |
"1" or "2". If not set, default is "1". |
CommPort : REG_SZ |
No default setting. Name of the interface to which the physical GPS hardware is connected; for example: "GPS1:". |
