Comment on command line util to encode/decode framed packets?

Hmm… I think looking at this from a radio perspective isn’t helpful. I found more resources when ignoring the media. Perhaps par2 or RAR would be useful? Generate error correction media first, then write to media.
Generally in radio, you could just request a retransmission, so I didn’t find much from that angle.
You might also find something useful when looking at tape backup programs. You’re not using LTO, but the principles are the same, so maybe there’s some tooling that would be compatible.

I did use
par2andtarto generate redundancy, but I still need a way to locate it in the bytestream. Tar doesn’t seem to reliably mark the start or end of files :/catloaf@lemm.ee 3 months ago
What are you using to control/access the tape? tar should handle that just fine, considering that’s what it was originally made for.

I’m using a regular off-the-shelf tape recorder, it doesnt have an electronic interface, I just press play and record manually.

So how are you retrieving files? Writing down timestamps? Tar should be able to find the start of an archive if you give it a little lead-in.
