Stanley Garge Door Status Indicator

[Brian Allston <bka@xxxxxxxxxxxxxxxxx>]

I had an older Stanley LightMaker grarge door opener.  The gear casing
cracked so I have replaced it with new a Genie opener but I would like to
restore the functionality of the Stanley garage door status indicator.  I
figure that I can do this with some normally open reed switches, a
Powerflash module and some macro sequences.  The Stanley door status
indicator (model # 3040) has three LED indicators.  The LEDs are green red
and yellow.
- green on = door closed
- red on = door open
- red blink = door obstructed
- yellow on = door secured

I have the house code set to "G" and I know that the door opener controller
head transmitted a standard "G1 ON" and "G1 OFF" to control a lamp module.
However, it sent non-standard message to "G2" and "G3" for controlling the
status indicator.  I assume that this is some form of extended data.

Can anyone provide the message info for controlling the status indicator?
Any info is greatly appreciated.
