Details:

Trying to get a grip on how to use SimulAVR, I tried with the "feedback"
example. First of all, please find two patches attached, which (0001-*)
simplifies the Makefile and (0002-*) adds instructions on how to run the
example. Well, the latter is what I found out so far, at least something
visible happens.

Running the simulator with the given firmware gives me no less than 910 lines
similar to these:

$ ../../src/simulavr -d atmega128 -f feedback.elf
WARNING: file hwport.cpp: line 165: Writing of 'PORTF.PIN' (with 101) is not
supported.
WARNING: file hwport.cpp: line 165: Writing of 'PORTF.PIN' (with 113) is not
supported.
WARNING: file hwport.cpp: line 165: Writing of 'PORTF.PIN' (with 117) is not
supported.
[...]

I tracked this down to commit 3f6a6882065 (Dec 2009), which introduced a "PIN
toggle PORT". About all chips, except the ATtiny2313, ignore this feature /
use the default value, which means false. Setting the default to true in
src/hwport.cpp makes all the warnings go away.

To be honest, I have no idea what "toggle port" means and why the default
apparently forbids to use a port. Given the numbers which are attempted to be
written, "feedback" tries to write out it's texts here.

Regardless of the default here, "feedback" doesn't do anything close to what
the README says. A connection is reported to be established, any keypress
other than a plain return results in an exception:

$ telnet localhost 7777

    (object "::guiMaster_sock6" method "::Master::ReadFromSimulavr" body line
34)
    invoked from within
"::guiMaster_sock6 ReadFromSimulavr"

After such an exeception, the connection is entirely unresponsive.
