Hi, I have been carrying out some
additional tests.
I checked the flush operation in my driver and it does print
"flush".
I then started looking at versions. I have discovered that
it works as expected if I use stream device version 2-5
instead of 2-6. In this situation I see a flush followed by
a write.
Kind regards, Alan

read at iocInit on many output records, but not on

Could this be from a "flush" operation? Your driver is
printing the message "device read"?
