Correct. In fact, bits 4 and 5 of input from port 0 read the last bits you wrote to 0 and 1.

Edit:
In general, if A is the last value written to the port on one calc and B is the last value written to the port on the other calc, the read value from bits 0 and 1 on both calcs is (~A & ~B), or ~(A | B), whichever you like better.

Thank you for the help.  I will revise the protocol with this in mind later.

Did you ever finish this protocol? Is there a revised document up somewhere?

Yes, but I've long lost it.  The protocol doesn't apply to USB, though, and I have to think of a better way to do it asyncronously.  CalcNet may also be ported.

I think you should be able to simply have one line be the clock and the other be the actual data.  That seems very fast in my opinion.  You could have the calcs fight over control, or you could have packets with a request to send or something.  I guess you would just have to know which one did the clock and who was supposed to be reading.

Graph, the clock and data line setup you suggest is the basis of what I2C uses. Only problem with I2C is that the standardized speeds are too high for our calcs. :(
A slowed-down version would be feasible, though.

Yay for the calcnet support! I wonder if Axe could get ported too :P not likely, unless you recreate all the bcalls, right?

No, Quigibo has expressed interest in porting Axe.  And TI-Basic support is planned.

Major necropost I know, but I was bored so I made up a File Format for the computer that KOS could use.

Thanks Binder News, but the great thing about KOS is that you don't need to define a file format - you could transfer any file whatsoever to your calculator as if it were a flash drive.

I am presently unable to work on it, but I promise I'll get more progress as soon as I can.

That's sad that you can't work on int, but I hope you will be able to soon.

Is that planned, or already finished? I need to work on that, since I can't work on TAO, atm. (Technically I am working on it, just not coding the massive amounts of USB fun stuff.)

Well, the ability to have any file is done, but the flash drive interface is planned.
