This is how you can do simple, more than two calculator chat. (With a
working IR transmitter/receiver) If the IR blankets the room, this is
good. Think about what would happen if you have 1 transmitting
calculator, and 2 receiving ones. The data transmitted from the
transmitting calculator would appear on both recieving calculators.
So you can have a multiperson chat. To keep track of whos saying
what, a name can be sent with every transmittion. Make sence? Of
course, there can be no comfirmation messages from the recieving end,
because if there was, the transmitting calc would recieve 2
confirmations, and get mixed up. This will make a choppy
conversation, but it will do. (there are software ways around it)
(ie, a hotkey to repeat what you just said, incase it got garbled)
Hope this makes sence... I AM TOTALLY inexpierenced with networks or
circuits like the ones neccessary for TI-85's.
