In order to determine if your DLT 2000 supports this feature, we have put together a tar file with the source and compiled binary to a C program that will function the drive and report the results.
You need to uncompress and un-tar the downloaded file, then run the getver program as root to determine if your DLT has the correct firmware level. If you have a C compiler, you can compile the source supplied in the tar file and execute that program instead. We have only tested it using Suns 3.0.1 C compiler.
See the comments section
at the beginning of the getver.c program for more details.
