[A83] Re: debuggers / simulated com ports
VTI does exactly what you are talking about. How do you think it loads all
the variables correctly? Most previous emulators had hacks that would
modify the calculator memory images to load programs. But VTI does it
correctly by actually sending the variables to the calculator. This assures
that it will always work, even if things change between ROM versions. This
is why on calcs without silent linking (82, 85, 92) you have to be in
receive mode to receive variables from VTI.
I don't remember if it sends as if from the graph link or from another
calculator. But if it's from another calculator, then it would be trivial
to change the code so that it sends from the graph link. Just change the
Machine ID byte. For example, with the 86 code, you'd change 86h (TI-86) to
06h (computer to TI-86).
You could also make something to interface with the virtual link.
