By "Port Driver", do you mean a GS/OS character device driver, or a
Print Manager Port Driver?  The latter has nothing to do with GS/OS -
it is associated with the toolbox, and is independent of any driver
that GS/OS might use.

If the Super Serial Card is in a slot set to "Your Card", GS/OS will
automatically generate a character device driver to use the card.
There is no fully-featured "loaded" driver for the SSC (or even for
the IIgs serial port).

I'm not aware of a Print Manager Port Driver for the SSC.

GS/OS has never implemented support for devices in "switched out"
slots/ports.  There is a partially implemented mechanism called the
Slot Arbiter, which is supposed to allow device drivers to be able to
access all seven ports and all seven slots, but it has never been
fully implemented, probably because of compatibility problems with
existing drivers and applications.
