xDriver Command Description
LDVX_NICMD_ENCRYPTION_ON_SEND=0x02 Use this command to enable RC4
encryption on the IP connection to
the RNI for all subsequent
messages sent to the network
interface. All subsequent messages
are encrypted until the
LDVX_NICMD_ENCRYPTION_
OFF_SEND command is sent, or
the session is terminated.
This command is ignored if
encryption has already been
enabled.
The xDriver subsystem determines
if the network interface supports
RC4 encryption. If it does not, this
command is silently ignored.
LDVX_NICMD_ENCRYPTION_OFF_SEND=0x03 Use this command to disable RC4
encryption on the IP connection to
the RNI for all subsequent
messages sent to the network
interface.
This command is ignored if
encryption has already been
disabled.
LDVX_NICMD_ENCRYPTION_ON_RECEIVE=0x04 Use this command to enable RC4
encryption on the IP connection to
the RNI for all subsequent
messages sent from the network
interface. All subsequent messages
are encrypted until the
LDVX_NICMD_ENCRYPTION_
OFF_RECEIVE command is sent,
or the session is terminated.
This command is ignored if
encryption has already been
enabled.
The xDriver subsystem determines
