I was trying to copy the stdiodemo to get the UART connected
to the UI port.  But still use a "magic" port to write debug output.
I guess I need to switch the magic port to a reserved address.
The real app (see below) uses two serial ports.

My AVR ignorance is showing. Sorry.

-d to what program? I thought simulavr.tcl was handling it ok.

Right now, not much.  When finished it will show how to write
a program which provides feedback to the program running on the
simulated AVR.  In my case, the UART really connects to a PC and
there is a custom serial protocol.  I will be writing code which talks
that custom protocol to exercise and debug the AVR program.

I want to configure simulavr to match the user's board and then
drive all inputs in a way that pushes their application.

The design goal is to use the UI interface to not have a GUI
but to interact with the AVR program.  Having a GUI to interact
with is nice but I am trying to figure out the basics of how to
interact via the "ui port" so I can build a test facility that is
aware of the application running and drives it.  It will eventually
be scripted and allow regression testing of the application.

I want to develop as much as possible of this in a generic
reusable fashion so other users benefit.  No one wants code
for our custom application but I hope the framework will be useful.

Does that make more sense?
