im sorted now, ebay didnt have any, looked on there.

dan, you will need a cable to "extend" the port so it can actually be reached easily. then there is the serial port cable that plugs into the extended cable.

ive got the port extender cable now (cheers tc ), and now looks like i just need to borrow a cable off someone for a few days.

needed the extension 1st as the alarm is being fitted a week today.
