If two calcs of the same type would want to communicate, one calc would j=

Actually, this is about the same design I thought up for link #1.
The problem is the fact that it won't work with the TI protocol (as you
stated), and isn't very useful. Look at my unofficial IR link schematics
somewhere. I hope no one actually tries to build or design any more IR
links that aren't compatible with the TI protocol, because it would be
much better to have a TI-OS -compatible link, like the one Keith
Burzinski is hopefully still designing.
Keith, are you still working on your IR link?
