Hi Zen,

There is a known serious problem in R4-11, which will be fixed with a new release ASAP.

The problem is that any attempt to connect to an asyn port driver before iocInit() will fail.  Commands that are normally executed before iocInit() and that require a connection to the port driver include, for example:

asynSetOption("myPort", 0, "baud", "9600")
asynOctetSetInputEos("myPort", 0, "\n")

This means that any attempt to set serial port parameters or EOS strings before iocInit will fail.  This is obviously a very serious problem.

I am not sure this is your problem, since you are using GPIB to CAMAC, and I suspect you are not explicitly setting an EOS string, right?

Do you see any errors at startup before iocInit?

Mark

Subject: Asyn R4.11

I have encountered the following error from asyn when I run my soft IOC with asyn R4.11.

2009/08/02 11:00:13.682 CAM:ASYN:IO: EOS TOO LONG

I get this error message each time an io operation is attempted on the GPIB device and the io operation is not performed.  The GPIB device is KS3988 CAMAC crate controller.

This IOC works fine with asyn R4.9.

Has R4.11 become more strict about sloppy programming?
Or do I need to set some asyn parameter, which for some reason either was not needed or did not matter with R4.9?
Anyway, I am not sure what the problem is and how to fix it.  For now I am back with R4.9.

Thanks,
Zen
