What's in this update
- Added possibility to steer FSK (both FSK channels are redirected according to TX focus and audio input is redirected according to RX focus).
- Extended router-firmware protocol:
- Possibility to start/abort playback/recording of CW/FSK messages
- Forced switching of keyboard mode in manual mode
- Audio output is no longer restricted to focused radio when audio codec is selected for at least one radio and SO2R mode is disabled.
- bug fixed: Removed glitch that occurred on all ACC pins at power up.
- Added another output lock that applies at startup. This prevents keying before first band data are obtained.
- NUM LED on PS2 keyboard is used in voice mode too.
