I did it with you all's help. We bought the DB9 kit from Radio Shack for $1.99 and the rj10 cord from off a phone at Goodwill for .50 cents. I used this Link to solder the DB9 to the rj10 and updated my hand controller to the latest version. Plugged it in to his ETX90/EC and we had initialization. It even listed the 90 ETX model in the handset. Know he can buy a goto controller and use my home made 505 cable to update. Many thanks fellas.
