What's in this update
- bug fixed: PTT1/2 settings, audio switching settings and TX monitor levels was updated on keyer mode change but was not updated when they was changed from router.
- Now PTT is automatically generated when FSK message is played even if no F10 or foot switch was pressed.
- In QSK mode the signal INHIBIT is generated for the duration defined by Keying Compensation parameter instead of PTT Lead. During this time the CW output is locked. Parameter "Keying Compensation" is sended to WinKey only in QSK mode.
- Now WinKey command 0A (Clear Buffer) drops Simulated PTT too.
