Re: [Simulavr-devel] Re: simulavr, again, and UART

Ted-

The sad thing is that "I don't know". The UART patch *may* stand alone, 
or it may require the 163 patch, but, I don't remember if I tested that 
or not, and, I simply don't get enough uninterrupted time these days to 
try it and find out (and fix it if it doesn't). All I know is that it 
works with what I had sitting here before I got pulled off the project.
