Just as I have suspected, my Kindle Voyage was in fastboot mode.
Code:

Running the proper command took me directly back to System Diags on the Kindle.

The rest was easy as should be. First:
Code:
(o)-Reboot or Disable Diags
Then:
Code:
(EXIT DISABLE)-Disable Diagnostics
I couldn't get
Prolific's PL2303 driver to work on macOS Mojave Version 10.14.4. Otherwise, minicom is available for macOS via
Homebrew. Thus, I opted for an Ubuntu 64-bit 18.04.2 VMware virtual machine. All necessary information for minicom setup and the rest is already provided by @noismaster on the
related thread.
I used an inexpensive
1.8V USB to TTL Serial Cable, three extensions, three crocodiles, two pins, and quite an unsophisticated modus operandi. See the attached thumbnail.
Further notes: Jailbreak survives the most recent firmware, 5.11.1.1. I have updated all the hacks from @NiLuJe's
snapshots. KUAL should be installed via ;log mrpi, though. KUAL-KDK-2.0.azw2 doesn't seem to work.
A final note: If it ain't broke don't fix it.
