Loop until keyboard input

Thinking about this a bit and maybe a way to do this is to implement
some control request on the ACM interface.

There has to be a simpler way though.  What happens when a word is
executed?  The jsr word is called in interpreter.f which will send an
ack back to the host.

Wait it should be possible to send a break signal to the ACM.
