Well Neil, I wonder if you can help me??
I have the combro too. But I run a Mac. So I have a USB-Serial cable bought from eBay..... the one recommended on here. I am running the ToxicCelery software which allows you to run the combo on a mac and I have the latest drivers for my Op system, The software sees the cable so I know the drivers are working... If I pull the cable out the drop down menu that indicates the port being used disappears ... so all seems okay.... but no response when shooting through the combro.
I am using the "snd" command on the combro.... does anyone else use this to test there output ? Does it actually work when trying to test the combro??
