Huh, what does this have to do with MACLISP (a now-ancient Lisp 
dialect), SHRDLU (the AI "blocks world" project), and IOC (a MACLISP 
built-in function)?

Seems to be a macro to issue I/O Channel commands.  
It looks like they can be rather safely ignored.

An FSUBR, actually.  As for what it did, calling (IOC G), for example,
was equivalent to typing Control-G on the input TTY.  Most of the
control keys were defined to set various TTY output control variables;
Control-G was a global abort to the top-level (similar to modern
Emacs).

Okay, how can I define it correctly?

Find a copy of the MACLISP manual, and write an emulator based on the 
specification there.  For instance, (IOC G) could be translated to 
(abort).  So it might look something like:

(defmacro ioc (key)
  (setq key (intern (symbol-name key) :package)) ; avoid package probs
  (ecase key
    (:g '(abort))
    ...))
