PKN10.cfg: configuration file, contents is described below. If
present, it is compared with device configuration in FLASH. In case
they are different, configuration from card is copied to FLASH.

monochrome bitmap fonts with the PKN09make.exe tool. It is
usually upgraded together with the firmware. The upgrade shall be
enabled in the local configuration.
