The JCA LU0 Connector uses dynamic link libraries (DLLs) to execute CPIC native calls to the communications server.
Different DLL files are provided for different operating systems and communications servers:
After you installed BTT, these DLL files are in the <toolit_root>\lib\comms directory. Rename the appropriate DLL and install it to a directory which is accessible through environment variable. The DLLs can be used both on client side and server side of the Communication Server.
