And don't even suggest a Windows computer, they are not allowed in the house.
This cable will no longer work on the newer Macintosh operating system ( Mavericks ) because the FTDI drivers and java and arduino software do not conform to industry standards. I can and do use the Tripp Lite Keyspan adaptors with JAVA apps all the time on Mac's. The output of those USB to serial devices is standard rs232 and not t/l level. What I need is a way to program the arduino boards with the 6 pin header t/l level interface that will work under Mac mavericks. The FTDI cable is not an option
