Your problem with double qoute is connected with tcl itself. It tries to 
interpret this double quote and then things go wrong. But, of course, 
it's also possible, that there are some bugs. The tcl/tk part of 
simulavrxx isn't maintained now. So, nobody seems to use it (expect you 
:-) ) and we have no feedback about it nor somebody, who keeps it running.

That's better. ;-) I use it too. (ok, if I had time ...)

Hm ... you can do that. But ... I have put all the stuff in ui directory 
out of pysimulavr.i. The reason - see before - it's not really 
maintained and it was written to support tcl/tk, not python. So, for you 
locally its ok, if it works as you want. But my opinion is, that this 
would not be a good idea to integrate it in python interface.

serialtx and serialrx are the counterpart to uart modul in simulator. I 
have made this completely in python as I tried to run amforth on 
simulator. If you like, then I can look for the code and send some parts 
to you as example, how to do that without serialtx and serialrx. I 
think, this would be too a example, how to connect some external stuff 
to simulation with pysimulavr.
