Yes, reading through that email thread, it looks like a very similar
issue to what Hamish was/is experiencing, with a similar dive
computer. Hollis and Oceanic are essentially the same company, and
many of their products are pretty much the same, with a different
badge - this isn't limited to dive computers.

My cable also has three pins.

The dive computer tells me its battery is fine

I haven't booted it for quite a while, but Windows (Vista) is also
installed on this laptop. I can test dive computer communication there
if that'll help work out this issue.

When I ran the setserial command, the latency_timer value was
automatically set to 16 - I didn't have to change it manually.
Subsurface successfully downloaded my last 64 dives. Unfortunately the
setting isn't persistent - when I remove and replace the cable, I have
to run setserial again.

I ran universal as requested, and here is the output. I'm guessing it
means more to you than it does to me. I tried running it both with and
without the setserial ^low_latency command, and the output is the
same.

rick at elmo ~/Downloads $ chmod 755 universal
rick at elmo ~/Downloads $ ./universal -v -l atom2.log -m atom2.bin -b
