Well, I've spent hours rebuilding PC(s) to Windows 7, finding pinouts on the web (leadshine's site) and I'm still no better off. Added to which is the frustration that I feel that whenever I'm able to some quality time on the machine its a public holiday weekend and I cant just drive to a supplier to buy a new cable.

If anyone has used ProTune on a PC can I please confirm the following settings with them.

RJ12 to DB9 Cable (the oh so special one!)

RJ12 Pin # Cable Colour DB9 Pin
1 White none
2 Black none
3 Red 2
4 Green 5
5 Yellow 3
6 Blue none

PC Settings: Windows [7 fully patched. No 3rd party firewall.]

Control Panel>System>Device Manager>Ports>COM1>Properties

Bits per Second: 9600, Data Bits:8, Parity: None, Stop Bits: 1, Flow Control: None
>Advanced> Use FIFO buffers: Checked, Receive and Transmit Buffer: 1

Please let me know what you have used that has worked. Thanks.
