8.5 Interface Input/Output Test (IOTEST)
Use IOTEST to test the input and output data busses of the signal processor interface.
When issued, the command causes 16 words to be read from the host controller, after which
the same 16 words are printed.
Typically, the controller supplies a "barber pole" input sequence consisting, for example, of
successive powers of two. If all of the output words are correct, one may conclude that there
are no malfunctioning bits in the interface hardware
