You do have control over everything, all the time. To use the usart IO ports as something different than usart traffic, just dont call the usart words by e.g. redirecting them to something that mimics the stack effect but does nothing on the port pins/expects something from them. Make sure, that no usart traffic comes in. With these precautions, use the DDR/PIN/PORT register just like you'd do on any other port. > In the recipes I saw how to turn off echo and I saw the code for > critical sections.

If you are short on code space, the usart code may be removed too, but that may be a creative challenge until the assembler is satisfied...
