No, none of it is possible via UART. But all you ask is actually possible via other means. For example all firmware versions (including the latest one, with disabled vendor commands and ATA extension to access SPI flash) do allow reading the same debug data from the ring buffer using vendor commands.

I never cared enough to actually fully decode it, but trust me - it is useless for most part.

I do not know
. If you really want I can decode the initial handshake bytes from your firmware, so you can check if you are getting the right data. There is however one useful thing you can do with the serial header - I'm not ready to discuss it publicily yet, but if interested - please PM me or better write to
