Subject: GPIB SRQ with StreamDevice

I'm trying to port some old GPIB/VXI-11 drivers to a soft IOC using StreamDevice, but one of the devices is slow to respond and requires the IOC to wait for a SRQ to read.  The old GPIB driver could handle this, but I can't find any way to do this using StreamDevice.  There is an "event" command in StreamDevice to wait for a bus-dependant event which looks like it should do what I want, but I can't find any confirmation that the GPIB bus support produces a SRQ event, or how to use it.  Web searches haven't turned up anything helpful.  Do anyone know a way I can do this?  Thanks.
