What's in this update
- Now it is possible to couple the keyer with two Station Masters via iLINK connection (one Station Master per one radio). It allows to merge their PTT sequencers and transfer decoded CAT frequency from keyer to both Station Masters.
- Optionally paddle can generate CW in VOICE mode too. In this case the PTT pattern for CW mode is used.
- CW Input to specified radio R1/R2 added to the ACC pin function list.
- Now mode "Reverse WinKey focus" applies to Steered CW Input too.
- bug fixed: Simulated CI-V protocol on ACC serial port could report an incorrect mode under some circumstances.
