I tried with two separate cables, to make sure One was a gigaware usb-A-serial cable 26-949, the other was a simple dongle one that windows 7 setup automatically I have even hooked it up to an XP box that had 2 dedicated serial ports, changed the serial cable extension just in case Still with no response I am at a loss Currently it's hooked up to a windows XP box running pd-extended 42-5 and hooked directly from the serial port to the BenQ projector The port was previously hooked up and working with a gentner echo suppressor so I know it works
I would check to see if the cable is a modem or a printer cable (does it cross over Rx -> Tx or not?). Also handshaking may be required (RTS/CTS or DSR/DTR).
