I think my point has been lost in the shuffle: it's not whether there  
should be a C function that lets you send text messages to the serial  
port with no wiring (albeit my comment about dependencies, and that  
it might be useful to incorporate it into tos.h somehow to prevent  
them). Rather, all I was saying is that maybe the function should not  
be named "printf."
