Hello, can any one help me sync my flexisign program with my PCUT CTN630? I am using an older version of flexisign pro 6.6 on an older laptop using the serial port. The laptop is running windows xp. My problem is is that in the flexisign program, I don't know which driver to choose. My choices are many in the production manager. My other cutter used "Roland" as the Manufacturer, and "PNC 1000 "model name. This doesn't seem to work. I'm using "Com1" port.
