Hamlib documents the spectrum scope on the IC-785x, so a rejected 0x27 0x11 is
not proof the command is missing — and taking 0x27 0x10 for the data switch
would have blanked that operator's own scope screen when OpsLog disabled it.
Both shapes were refused within 96 ms, so neither was a timeout, and guessing
the next subcommand is how the last two rounds went. The retry now logs the
second attempt's own error and the failure points at the CI-V trace.
