asyn R4.10, R4.11, R4.12

["Szalata, Zenon M." <zms@slac.stanford.edu>]

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
