Keypress events (aka "!KPE" messages)

I'm running AD2pHAT with an Vista 20SE panel (ADT Safewatch Pro 2000). I'm interesting in capturing 'Keypress Events' from my physical ADT keypad so my python-based home automation software can repurpose the 4 function keys on the physical keypad. Reading the protocol document, I'm led to believe I need to enable KPE messages via CONFIGBITS and then I should see !KPE messages when I press the physical buttons on the keypad. Specifically I'd like to be able to receive a message event within my python program whenever one of the function (panic) keys on the physical keypad is pressed. Obviously it's not working for me or I wouldn't be here.
To try to sort this, I'm using ser2sock and viewing the AD message stream via a putty window. My config string is:
!CONFIG>MODE=A&CONFIGBITS=ff07&ADDRESS=31&LRR=N&COM=N&EXP=NNNNN&REL=NNNN&MASK=ffffffff&DEDUPLICATE=Y
I have a hunch this capability was never implemented as I would expect to see a "device.on_kpe_message" type event via the python library, but I can't find anything that seems to resemble that. What am I missing?
Thx!
