Re: Using a TI-83+ or TI-84+ as an auxilary controller
I believe that the link used between calculators is not straight-up TTL/RS-232. IIRC, it is more complex than that.

I would recomend asking for info on a more dedicated forum for the TI link interface. I know Cemetech is a group of some serious TI-8x fans. (There's a Calculator hardware forum even.)

You can use one of the old black/gray links, which will go to RS-232. Still doesn't help with the protocol, though.
