Yes.  I wondered how one was supposed to do
that myself.

I wonder if it wouldn't be useful to have
an alternate simulavr-tcl executable
which could read a user provided Tcl
file to do the connections.

Ideally it would be possible to use the
same application plugin mechanism for
my simulavr.tcl and the C++ simulavr with
Tcl embedded.

But this is all just thinking now.

:)  I wondered about something like this myself
CORBA ORBS have a way to take their arguments
from a command line and leave you others.  So your
main calls "corba_main" and when it returns you
are left with the argv/argc arguments it didn't
interpret.  This would be interesting so there
was a simulavrxx_main framework which could be called
from any C/C++ application.

I think all of this is very close to working.
FWIW I don't see how writing to the SPI registers
(SPDR?) is getting propagated.  

Maybe there is some unmerged code in your tree.

I have some indoor work myself since
Huntsville and Atlanta are in for a rainy
and stormy weekend.
