For example, according to the documentation of my INKA braille
display, to overwrite the flash memory you have to send out a packet
containing a command, the blocks of data and a check sum, which is not
likely to happen by accident (unless you're debugging braille display
software that uses the INKA packet protocol and transmits spurious
commands, perhaps).
