Flags (4 bytes): An unsigned 32-bit integer that is read by the server and used to set the Filter Keys parameters.

Flag	Meaning
FKF_FILTERKEYSON 0x00000001	The Filter Keys feature is enabled.
FKF_AVAILABLE 0x00000002	The Filter Keys feature is available.
FKF_HOTKEYACTIVE 0x00000004	The user can turn the Filter Keys feature on or off by using the default hotkey (holding right SHIFT for 8 seconds).

WaitTime (4 bytes): An unsigned 32-bit integer. The length of time, in milliseconds, that a user has to hold down a key before it is accepted by the computer.

DelayTime (4 bytes): An unsigned 32-bit integer. The length of time, in milliseconds, that the user has to hold down a key before it begins to repeat.

RepeatTime (4 bytes): An unsigned 32-bit integer. The length of time, in milliseconds, between each repetition of the keystroke.

BounceTime (4 bytes): An unsigned 32-bit integer. The length of time, in milliseconds, that has to elapse after releasing a key before a subsequent press of the same key is accepted.
