> Why not bring one more to read the binary dump too?

For one, because it is not packaged for my distribution. For two, because I get exactly nothing in return. All binary logs do for me is forcing me to use an additional tool.

POGO-E02. I really don't know how old this is, but it has USB-2 and I bought it 2 years ago, though it was marked as classic then. Maybe 2009?

> and when doing forensics, we usually do that on a reasonable machine, where all the tools we need are available

I'm normally doing that at my own environment, with the tools I am used to, and on my machine. Nothing of that includes a binary log viewer.

A few years ago, I was called by the manufacturing team to troubleshoot a simulator bench of our own system. The bench had been developed 15 years ago by a subcontractor and was working happily since then. The issue was pressing because it could halt the manufacturing line. I had 0 information or documentation on the bench. All the respective owners had been gone years ago. I was quite happy when I found there was a basic logging system on a serial line.

I think is it more telling about lack of organization rather than wrong technical choice, but sometime you have to deal with legacy systems and it is good to be able to rely on something as universal as text.
