Dear all,
 I am trying to communicate the gpib device with asyn.when running application,there is no error. But when I use the command dpf,it says:
epics> dbl
PSM6003:PSM6003Record:current
PSM6003:PSM6003Record:current-step
epics> dbpf PSM6003:PSM6003Record:current-step 0.5
DBR_STRING:          0.5
epics> libgpib: IBOPENDEV ioctl failed
libgpib: ibfind failed to get descriptor
2008/01/11 15:30:20.803 L0 addr -1 : EDVR 0: OS error.
2008/01/11 15:30:20.804  151042680 autoConnect could not connect
 
The gpib_config file is:
interface {
        minor = 0    
        board_type = "ni_pci"  
        name = "L0"    
        pad = 0
        sad = 0
        timeout = T3s  
        eos = 0x0a     
        set-reos = yes 
        set-bin = no   
        set-xeos = no  
        set-eot = yes  
        base = 0x310              
        irq  = 7     
        dma  = 0 
        master = yes

}
Have a great weekend!
