What's in this update
- Some changes in keyer protocol and settings format was introduced to be compatible with router v5.1.0. Hence firmware MUST be upgraded and power-up settings MUST be again stored to EEPROM of keyer.
- Firmware utilizes extended frequency/mode information from router CAT decoder:
- Keyer mode follows TX mode.
- Any of RX, TX, operating, VFO A or VFO B frequency can be displayed.
- CI-V can report any of those frequencies too.
- bug fixed: Sleep mode was permanently enabled regardless of settings.
- BackSpace on PS2 keyboard now functions as ESC.
