Hacking TI Calculator Interface

Hello, all:

        I know that this really doesn't fit here, since I only bought this calc
yesterday, but I figure that someone here may know...

        I bought a TI-85 graphing calculator, and it has a 3-wire computer interface.
It seems that for $40, you can buy a cable adapter to hook it to a PC's COM
port. Software can be gotten from TI's Web site.

        I don't want to pay $40 for a DB-9 connector and a 3-wire headphone jack. I'm
guessing that the interface is a software-handshaking 3-wire RS-232 setup, but
before I hook something up to the calc, I wanted to ask if anyone has this
calc and can shed some light on it.
