Some Windows based loggers are not able to share single virtual COM port for radio and CW/PTT. You can solve this problem with microHAM USB Device Router software.

For example if your computer have two hardware COM ports COM1 and COM2 then create COM3 and COM4. If you have installed additional serial card with COM3,4 create COM5 and COM6. If your logger does not support CW/PTT at the same port, create third COM port.
