Serial port diagnostic lead problem

[Mr Tivoli Blue]

I have bought a diagnostic lead from ebay which is a serial port lead.

When plugged into either serial port and connected to the car (1994 Golf 1.8 driver) i get port ok interface not found. No matter what i do i cannot connect to the car.

Questions

a. Will i see the interface lead if it is only connected to the PC?

B. Must the ignition be on for it to work?

C. which software should i use? The lead is third party and has KKL com Written on it.

D. are there any special driver i should load?

I am curently using vag com 409.1

I have tried other diagnostic software with the same results.
