Hello,

I am unable to send triggers to EEG using parallel port. Although the code does not show up any error and is running successfully, the triggers are not being sent to the EEG device. Is there anything else, that should be checked besides the port address for sending triggers? I have tried the solutions mentioned in the below attached links

Any help would be greatly appreciated.

Thanks,
