Hi everyone~
I'm trying to connect a scope via linux-GPIB. The driver had been
setup and read/write to the scope was successfully tested with
"ibtest"

But when typing in iocsh the command
GpibBoardDriverConfig("L2",1,0,3,0)

I got the error:
2011/03/14 21:48:44.176 L2 addr -1 : EDVR 0: OS error.
2011/03/14 21:48:44.176 L2 addr -1 : EDVR 0: OS error.
........
libgpib: invalid descriptor
libgpib: invalid descriptor
libgpib: invalid descriptor
........ alot of repeat lines.......

Looks like the GPIB device address was not set correctly. However, I
can find no hints in the asyn document for the problem. Is there
anything I missed here?
