Autronic Serial - Windows not working but Pi works

Hi,

I have been running my Pi Realdash for a while without any issues.

Switching to a Windows 11 SBC, I can use my USB to Serial converter with my Autronic SM2 ECUCAL software on COM4 fine.. but Realdash can’t communicate with SM2.

I have set the Autronic data source and Realdash sees the COM4 for the USB to Serail Adaptor, 9600bps. But when RD tries to connect to the SM2 data stream, all I get is the “Connecting to” popup continuously flashing and no data.

Appreciate any tips thanks.
