Herb,
Thank you for your answer and help.
Unfortunately, i can send commands but they are too many characters and PuTTY stops sending
to the NanoVNA.
May be, my FW version " 0.8.4.6 - 96kHz ADC, 800Hz, sweep_points 201, by DiSlord " is not compatible with serial ?
I will continue to search a solution.
Best regards,
Rudi
