Need pinout for Kyocera 2235 data cable

[ki7ll]

I would like to build an interface to control a Yaesu shortwave radio.
I have a pinout for the phone end of the connector but it does not say what the signal for each color wire should be,(ground,dc,txd,ect,ect). :?:
Any help on this one will sure be appreceiated.
