The last version I posted can be found at www.ece.arizona.edu:/~john.
I have been using it quite extensively for the last few months on a
2.2.6 machine. Mostly it has been small transfers, so I haven't been
using it at heavy load. It appears to be quite stable under those
conditions.
I have tested it on another 3.0 machine, but I haven't been using it
for real work.
I made some extensive changes in order to support catching SRQ's using
the poll() mechanism. I almost have it, but there was one thing that
I couldn't get to work, so I haven't posted it yet. The version on
the web page is the one I am actually using, along with a bunch of
documentation.
