Ok, I know have a few DB9 adapters that need to be put together to attach to the serial connection on a COmdial DXP switch.

Try as I might, I can't get it to work. I have already ruined two of these so clled easy to create adapters.

Can someone tell me in plain simple english, which color wires go to what numbers pins.

I have the following wires;

blue --- Pin
red -------Pin
yellow ------ Pin
white --------Pin
black --------Pin
Green --------Pin

I must have tried all possible configuration EXCEPT the correct one.
