The anacomp example does it as well. If i enable the tracing window in 
checkdebug.tcl i see, that the emulation is running as long as the debugger 
starts up. Once the debugger is running, the trace stops and the simulation 
is under control of ddd/gdb.

I will create a simple test set.

That's not what i wanted to know. In fact i did find it in the meantime 
myself. I was asking for the pipe on port 0x20. I didn't know what exactly to 
ask for since i only found it mentioned once in the archives.

I added the same function to port 0x66 on the mega128 and it works fine, 
thanks!

Yes, that's what i am using now. Great!

The code does debug and info outputs and i just wanted to keep getting them. 
On the real device this is sent via rs232, but i the emulated rs232 is 
slower, has the problems with the special chars. I just like the pipe 
thing :-) And since my rs232 code is not the one i have problems with i don't 
care if it isn't included in the simulation.

And yes, of course i'll be using the debugger. That's the whole point of using 
simulavrxx.

Ciao,
