Umm. We don't have /dev/anything.

One creates their own putchar/getchar functions and associates them with a 
particular stream. That way you can read/write to a UART, or write to an LCD, 
or whatever peripheral comes to mind that can accept some sort of I/O. There's 
just no basic assumption that any particular I/O device exists on an AVR.
