HendiCtrl.cmd() previously raised a bare "Communication error" for any
non-OK response, discarding the firmware's actual reply. It now
includes the raw echo/answer bytes, and --debug prints every
request/response. Using this, the rejected R1 during lockout turned
out to be an explicit "ERR:Invalid state" reply, not a timeout.
Also flashed and retested v1.16: plain reconnect (no --reset) now
recovers from the lockout reliably (4/4 trials), fixing the
intermittent behavior seen on v1.15.
