What's in this update
- PA PTT output can optionaly generate also LNA PTT (with PTT tail)
- PTT2 can be again generated from foot switch like before v1.8 (PTT1/PTT2 from footswitch are always delayed)
- New flag "FSK busy" is generated. This allows to host applications turn PTT off in the right time.
- Function TUNE, started with asterisk on key pad, now generate PTT in advance before CW to overcome problems with some radios.
- Added possibility to temporarily suppress keyboard evaluation. This can be used by router to handle voice message recording/playing from keyer keyboard without mixing with standard function of keyboard.
- support for digi keyer
