On ticalc.org, there is a program,
http://www.ticalc.org/pub/85/asm/programs/zshell/remote92.zip , where you
can control the TI-92 from the TI-85 when the TI-92 is in remote mode, and
I've gotten it to work. The program is very limited, though, and you can't
type letters (except a couple, I think you can type 'x'). It has a few
commands you can type, like solve(). I would assume this would work with the
TI-89 also, as long as the getKey codes are the same.

I don't think it will work through the TI-Graph Link cable, but maybe with a
parallel or serial cable it would. I don't know very much about this, but I
think the TI-Graph Link cable has a built-in protocol that it uses, and
remote mode only accepts and outputs raw ASCII.

One possible application for the remote mode besides the one used by the
program linked above is, if you CAN use remote mode with a computer-to-calc
cable, you could send expressions and functions to the calculator to be
evaluated and get the result. You could set up a web server with an HTML
form where people could enter expressions, and a server script would send
them to the calculator and display the answer on a web page! But then
somebody could crash the calculator by typing in "Lbl x:Goto x" or
something, so you'd have to set up some type of safeguard or timer to break
the operation if it took more than 30 seconds. That would require an
assembly program on the calculator, because the ON key doesn't have a getKey
code.

    I read some information about something called the remote controll mode.
If you haven't heard of it, press (on your calculator) [home], [f5],
[diamond], [apps], [alpha], [r]. It should look like a normal home screen,
but you can't input anything. It's 'supposed' to be able to connect with
hyperterm or a terminal emulator through the GraphLink. I can't seem to get
it to work! Does anyone know the correct settings for this? Or does it even
work?
    I called technical support, and a _snobby_ guy told me ". . . when your
entering the debug mode, information about that is not for the public. I'm
sorry, I'm not allowed to help you with that". I don't think he knows what I
was talking about, he thought i was talking about the Self Test. Maybe i can
get a hold of some staff member by email (they seem to be nicer in
non-real-time).
    Although if anyone knows about this 'feature' please tell me!

    Thanks!
    Kyle
