RTL-SDR dongle and COM1 port

Post by RSOR14 » Tue Sep 15, 2020 6:20 pm

Hi,

RTL-SDR dongle is running OK but it blocks my COM1 port.

I have an own software peice which is communicating to a hardware connected on port COM1 via serial cable.

When RTL-SDR is running via SDR# I can not open my software. My software connects immeditely to port one and opens my GUI when shutting down the RTL-SDR dongle.

Any tips how to overcome this problem.

No, I can not use any other serial port or USB port as the program is not able to read any other port then COM1.

Thanks and regards Rainer
