How to detect Login Screen \ Character Selectioin \ Disconnect

[attn]

Hello,

I'm trying write simple program (plugin) that auto-connect, select character and reconnect to WoW (if it disconnected).

Finding TLS pattern in wow memory gives signal that character successfully loaded but atm I can't find how to detect next events:
a) login screen loaded
b) character list loaded and
c) wow disconnected.

Disconnecting can be detected by running netstat with filter on port 3724 but may be there are more elegant solution.

Thanks.
