Added function for BlueMod configuration: Investigations of connection problems showed that there is a problem if the module is not able to forward data fast enough. The bottleneck in direction of microcontroller may be solved by increasing baud rate. To be backward (bootloader) compatible this is done temperoraly during every startup Added function for signal stregth evaluation: Quality of data connection may have an impact on stability => added function to visualize current state of connection. The evaluation may be requested remote using 'l' (0x6c) or by pressing next button while in service mode Cleanup Disconnection procedure: Disconnection issued by OSTC was realized by simply switching of the module which might have a negativ impact to remote devices. Second reason for change was that, e.g. in case of a timeout on OSTC side. a remote device might have continued sending firmware data causing OSTC to interpretate firmware image as service requests. E.g. resulting in a corrupted configuration. Instead of just switching off power a disconnection request is now send to the BlueMod. Decreased size used for large data receiption: Depending on device speed firmware transfer might be really slow. By decreasing the block size a short (6 seconds) timeout per block may be kept while the sender has more time for transfering the image

// 2018-01-01 jDG:
//  - the exact address is fixed in linker script CPU1-F429.ld,
//    so that every font can be used even when not included in the actual
//    binary (boot-loader, fonts, or firmware).
//
//  - Actual font data is defined by the OSTC4/FontPack project, that shall
//    be loaded before the firmware is executed.
//
//  - Font directory starts at address 0x081E0000. Each header is 12 bytes.
//    A 0xFFFFFFFF (32 bits) marks the directory's end.
//    It is stored between __font_directory and __font_directory_end;
//
//  - Font data (chars) is stored after 0x08132040 (end of font's SFirmareData).
//    So there is space for 0x081E0000 - 0x08132040 = ADFC0 = 694 KB of fonts.
//    Actual data is stored between __upper_font_data and __upper_font_data_end,
//    and uses 0x081b9a3a - 0x08132040 = 879FA = 542 KB.
