Reverse Engineering PM3 RS232

I want to link my PM3 to database for serializing devices. I think the easiest way to communicate to pm3 will be rs232.
 
Anyone know the format of image? I am thinking to use a device in between the pm3 and PC with ipe to read and pass along communications. I was just wondering if anyone has already figured this out.
 
I found some hints here:

Why use a PM3 where you have to reverse engineer it?  I used a softlog ICP2 for programming:
http://softlog.com/index.asp?page=ICP2%28G3%29&parentid=2
They have a DLL to control it.  At least then you'd have a documented, supported interface.
 
Who knows what microchip will change down the road?  I'd be afraid that plugging the PM3 into a computer with a newer version of MPLAB would break things.  It did for me with PK3CMD, and that was just from the command line.  Some firmware update did something wierd, so I had to load the older MPLAB and reprogram my PICkit3.
 
Disclosure: I have no association with them other than as a happy user.

Serializing devices? Please elaborate.
Microchip offers ipecmd and also SQTP feature. Please refer those.
