From the project
Capture the output from a computer's parallel printer port.
NOTE: Only the top/default DB25MicroUSBBASIC version is tested and known good. All other versions are untested guesswork.
The device appears as a usb-serial adapter to the modern machine. Drivers are standard in any modern os or platform. Use any serial comm program like PuTTY or TeraTerm or minicom or gnu screen etc to read the COM port. It doesn't matter what baud rate you select in the comm program.
