I think it would be a very helpful feature to add to IO ninja to just be able to save a log as a raw binary file for each direction.

It's very easy to achieve with a log filter/observer plugin script.

However, I can't say I find it very useful to have two raw binary files containing just the raw bytes flowing in each directing -- how would you reconstruct the mapping between requests and replies in case of some non-trivial conversation between the client and server?

I often have serial port logs that I just want to save to a bin file as-is, and I end up closing IO ninja and just going back to something like CoolTerm which supports this natively.

If it's a uni-directional log kind of thing (e.g., your device keeps dumping debug printfs to a RS232, and you want to save it to a file) -- this can be done using Session Linking. Open a Serial session, open a File Stream session in Write-only mode and point it to some file, then "link" those sessions. Everything that the Serial session reads from the device, will be redirected to your file.

it also supports recording directly to a file, in case the computer crashes or powers off during logging

Actually, IO Ninja always keeps its logs in disk files. When you "Save Log", the temporary .njlog file simply gets copied into the file you select. But if you "Save Session", those .njlog files will get stored in the specified folder, and you will know exactly where to find them in case of a crash.

But once again, a dedicated plugin that would explicitly save RX to one file and TX to another is quite easy to implement. I don't know, maybe we should add it to one of the upcoming releases as an official plugin (or a sample)?
