I'm not familiar with any GPIB bugs on the 5370A, but I moved your code over
to C and ran it on my 5370B via a GPIB-LAN adapter. The test app failed
after ~6 hours with a Winsock timeout error. I'm thinking that was caused
by a power glitch, though, because I actually had to power-cycle the
I just got one of the new networked GPIB controllers, and I've been
having some issues. I'm not sure if it's the Prologix or the
instruments, or both.
With the 5370A, I can get samples for some period of time ranging from
about 2 to 4 hours before the GPIB controller stops responding. I

If the 5370A problem is actually the 5370A gpib controller bug, then I
don't think it can be reproduced with the 5370B; I'm pretty sure that
was fixed in the B model.
However, if you want to give it a try, here's what I do (you'll have to
interpret, but it should be pretty clear):

YI don't use read-after-write, and I explicitly set it off before
reading. However, I did try it once just for fun, and it does work as
expected.
The 5334 doesn't seem to assert eoi, so I do

Bill,
I recall there was some question on the Prologix unlisten, but I suspect
you're seeing a 5334A issue. While testing my driver at max 5334A
throughput, I found found you cannot trust a ++read until the status byte
returns data ready, else you may get the previous reading. That would happen
