They didn't.

The serial-port protocol on the Mac is RS-422.  I think I remember that RS-232C
is a subset of it, or at worst can be handled from the port.

Note that the ImageWriter II uses an RS-232C connection.  Worked that way on
Apple//'s and even ///'s.  Straight plug-in on the Mac from day one.

(Hope the numbers are right...but then, what do I know?  I just write about
software.)
