Getting custom object data

I would like to retrieve some data from objects created by a 3rd party ARX
application. There is no ActiveX interface provided for these objects.

However, when the application is loaded, I can see the data I need using the
autocad LIST command. So my questions are:

1. how can I get the text from autocad command line using ActiveX? I know
that the last line is in LASTPROMPT variable, but I need also few earlier
lines (the whole output of LIST).

2. is there a smarter way of accessing this custom data?

below is an exaple of what list command shows:

Select objects:

Layer : Jp-TEKSTI
Handle : 10ED8
Connections : 10ED5
position, X=73900.0000 Y=21025.0000 Z=2400.0000

it is the "Connections" data that I want to retrieve.

 

figured out a solution in question #1:

I can sendcommand copyhist, then I have the command line history in
clipboard.

But the question #2 still remains, especially because I think the above
method is slow when there's a lot of objects.
