screen-scraping

We have a legacy system that is essentially a glorified telnet interface. We cannot use an alternative telnet client program to connect to the system since there are special features built into the client software they have provided us.

I want to be able to screen scrape from this program, however that's proving very difficult.

I have tried using WindowSpy and Spy++ to check the window text and it comes up blank. It's a custom C program written by the vendor (they have even disabled selecting text). I'm really looking for a free option and something I may perhaps be able to use in conjuction with a scripting language.

It seems the only ways to grab text is directly from the Windows GDI or from memory, but that seems a little extreme.

Can anyone recommend any software/DLLs that might be able to accomplish this? I'd be extremely appreciative.
