Thought I'd try plugging into my Mac and bingo, I have comms connection.
Running through Belkin clip on hub usb to usb.
I always thought that you needed to run it through a usb/db9 cable to work with a Mac.

the on board usb is a sub-> serial connector.

Digging up the post,

So freaky, is it running now?

Hi abs, nope it's not fitted yet. Been so busy that I've not had a chance so looks like I'll get a fairly local guy (Skuzzle on MX5Nutz) to fit it once I've got a few other bits sorted.

Thanks for the answer
