Well, if you do 'man gpib' you will see references to /dev/dev1 - /dev/dev16. These are the devices for gpib address 1 through 16. If you want to call your device /dev/dvm, simply make a link from /dev/dev2. | (iii) if questions (i) and (ii) clearly demonstrate a total lack | of understanding, what am i missing ? Well, if you hope to program for the board at all, I would strongly suggest getting the manual from National Instruments that documents the library interface, referenced on both the manpage and the release notes... -- Dave Olson Life would be so much easier if we could just look at the source code.
