Doosan communication wire

[speedrider]

I have a Doosan 4020 and a 3016 with 21i MB controllers. They have RS232 ports. I need to make a cable (25 pin machine to 9 pin computer) to hook up to the serial 9 port on computer. Does anyone know what the pin out configuration should be?

Thanks

Here's a page describing standard RS232 wiring for both 9 and 25-pin connectors: http://airborn.com.au/serial/rs232.html

You only need a 3 or 4 wire cable, shielded if possible.
