Hi Mark,
Actually I made a mistake in my original email.  I am only using asyn.

Here is my st.cmd file:

zms@ilc-esb11 $ less st.cmd
#!../../bin/linux-x86/cam

< envPaths

cd ${TOP}

## Register all support components
dbLoadDatabase("dbd/cam.dbd")
cam_registerRecordDeviceDriver(pdbbase)
vxi11Configure( "L0","134.79.64.25",0,0.0,"gpib0",0,0)

asynSetTraceIOMask( "L0",12,4)
asynSetTraceMask( "L0",12,0xff)

## Load record instances
dbLoadRecords( "db/blink.db","P=CAM")
dbLoadRecords( "db/camio.db","P=CAM,PORT=L0,A=12")
dbLoadRecords( "db/iosetup.db","P=CAM,V=/nfs/slac/g/testfac/esb/")
dbLoadRecords( "db/timestamp.db","P=CAM")

cd ${TOP}/iocBoot/${IOC}
iocInit()

And here some of the output the IOC generates:

Thanks Mark,

Hi Zen,

I'm not sure what the problem is.  I am using streamDevice with asyn
R4.12 and I don't have problems.  But I'm using serial, not GPIB.  Eric
Norum is the one who knows most about GPIB.  Hopefully he's getting
settled in Berkeley and will be able to answer your question.

Can you send the exact output of the IOC?  The only occurence of the
string "EOS TOO LONG" that I can find in asyn or streamDevice is in
asynRecord.c.  But you say you are using streamDevice, not the
asynRecord, to talk to the device?

Mark

Subject: asyn R4.10, R4.11, R4.12

I have a simple soft IOC which uses asyn and streamdevice.  It does IO
with KS3988 GPIB CAMAC crate controller.  The IOC works correctly with
asyn R4.9.  I have installed asyn R4.12 and my IOC does not work with
asyn R4.12.  I get the following message: "EOS TOO LONG".  I also tried
asyn R4.11 and R4.10 I see the same message with these the two versions
of asyn as I see with the latest.

How do I overcome this difficulty?  Do these newer versions of asyn
require that I make some change to my IOC?  Can someone help me with
this, please?

For now I am forced to stay with asyn R4.9.

Thanks,
Zen
