You can't.  It doesn't have any slots.  This isn't what John was
asking, anyway.

Apple had intended to release an AppleTalk interface for the IIc, and
included firmware support for it in the "UniDisk" version of the ROM,
but it was never completed, and the firmware was removed in a later
version.  It would have involved an external box which contained its
own microprocessor.

The IIc has default settings for the ports (stored in auxiliary memory
screen holes) which can be changed using the System Utilities (they
are lost when you turn off the computer).

Software can override the defaults by sending commands to the firmware
(or by bypassing the firmware completely, as is usually done by
communications software).
