Is there a vector I can hook a routine to? I have a ton of code I'd love to

It's the tpdd client that creates an inloaded file in the RAM filesystem,

The only thing ts-dos is doing differently is it's treating .ba files
according to the rules of .ba files, as dictated by the main rom. It's
not a ts-dos thing. teeny and floppy etc have to do the same exact thing.

to me that there was a needed repair.
I'm also interested to understand more about what's going on with the
backpack.
You said it had to do with handshaking signalling and loopback, and what
sounds like a powersave mode
Some of the original M100s have the wrong resistors in part of the RS232
handshake circuit. The voltage drop is so high that with the signal looped back
it is just barely sufficient. The Backpack eavesdrops to know when to power
itself back up and this minuscule additional load is too much.
