Hi,

how are you starting BCI2000? From a batch file, from BCI2000Launcher, or directly from the command line?

Best regards
Jürgen

Using BCI2000Shell.exe
But I'm getting this error I mentioned in the operator system log.

Thank you very much for your response.

BCI2000Shell works for me as expected on Windows 11.

If you give it an argument without qualifying option, it tries to load that from file and execute it as a script, hence the error message. To force the connection to "localhost:3999", use "--Telnet localhost:3999".

And is there any way to add that instruction so that it's taken into account when BCI2000 starts?

Thank you very much.

To use BCI2000Shell interactively:

Code: Select all

BCI2000Shell -i --Telnet localhost:3999
To execute a command:

Code: Select all

BCI2000Shell -c "ls" --Telnet localhost:3999
To execute a script:

Code: Select all

BCI2000Shell "myScript.bciscript" --Telnet localhost:3999
