Some kind of a mixture of
http://amforth.sourceforge.net/recipes/interrupts.html and
http://amforth.sourceforge.net/recipes/redirect-io.html
should do what you want to do (and perhaps the multitasker)

I'm too lazy to convert the assembly usart word to forth
code. There *was* a technical reason to use assembly for
interrupts in the first amforth versions, but that is
no longer the case. Never change a running system ;)
