AUDIT_NETLINX_SESSION_EVENT

I don't know how closely you looked at the newest Netlinx.axi (v1.55) released for supporting the new Listview boxes, but there was another bit added in there unmentioned in the readme:

(* Added v1.54, to support AUDIT_NETLINX_SESSION_EVENT *)
LONG NETLINX_LOGIN_SUCCESS = 0;
LONG NETLINX_LOGIN_FAIL = 1;
LONG NETLINX_LOGOUT = 2;

Anyone know what that's all about?

Looks like support for logging login attempts.
We're seeing hack attempts shown in TELNET at most sites where the NetLinx is exposed to the internet, even briefly. Get enough of them, fast enough, and the netlinx can't handle it and goes dead until a reboot. This might be part of a scheme to count fails and manage a period of unavailability instead of an unmanaged lockup.

Or not.

Could also be/include instances where Netlinx Studio connects. Would be a nice security feature in general to let a user know someone is connected to their system, just like you can know when someone is using VPN on a touch panel.
