Experimental Physics and
I have a device on my Linux IOC, using Asyn GPIB. The device works on the IOC and, connected with EDM - is controllable.
When the device is turned off I get an error message: asynError in write:
GPIB0 writeGpib failed ENOL 2: No listeners
The function in the proto file uses exception @replytimeout, (and tried again with @writetimeout)but that never executes, which I would expect (I queried a device, it's not there, I should have a timeout). This works on TCP/IP devices, just not GPIB.
Does anyone have any thoughts, or hacks, or updates on getting GPIB exceptions to run the proto file exception commands?
Also when I try using the @writetimeout exception to more closely mimic the error message, the IOC crashes on boot, not even an IOC command prompt, which looks like a separate problem, any help on that would also be appreciated. Error message requests me to mail teck-talk, and is:
A call to 'assert(dbLockIsInitialized)'
by thread 'cbLow' failed in ../dbLock.c line 239.
