Yes.  They are "MULTIFUNCION" cards in that the card type is
multifunction, but they aren't multifunction cards because they have
only one function.  Now that's confusing :-).  The CIS I've seen on a
few of my cards didn't list its function as SERIAL, but rather

The standard is clear on this distinction.  It says that when the card
is listed as a MULTIFUNCTION card as its function, then it means that
it has multiple functions, but that these functions aren't represented
by the CIS and other configuration mechanism as having discrete
