Nope. I get AAEA back from that command (like I should), but it
doesn't change any behavior.

The actual "read serial number" command still fails with no data,
whether I do it as 4 bytes at offset 12, or 16 bytes at offset 0 (like
the Mares app).

After switching to the 16 at 0 version, that is *exactly* the same
command sequence that the Mares App does first too.  But when the
Mares app does it, it gets the 16 bytes of data.

Weird.
