Extending RUMBA/3270 client using COM interface or EHLLAPI

Question

Hi All

In my application i want to listen for any RUMBA/3270 (It is a 3270 emulator) screen update/event which i can capture and get the text/byte stream coming from mainframe. Once there i can use that stream for data mining.

In the RUMBA data-sheet they have mentioned that RUMBA 3270 emulator could be extended either by using EHLLAPI or COM interface.

Now the problem is I don't know how to extend/control RUMBA using EHLLAPI or COM interface. Although there is one C# example on Code Project which demonstrates the use of EHLLAPI, but it is a standalone application. I couldn't find any COM related stuff for the same.

Kindly suggest how to extend/control RUMBA.

Thanks..
