PostScript to FAX converter?

[SEARS at MAIL.PHYSICS.LSA.UMICH.EDU]

Does anyone know of software that would convert a PostScript file to
the format required for transmission by a FAX modem?  I know *nothing*
about the FAX bit stream format (don't really want to learn about it,
either!)  A program that came w/my Dell laptop made me think a
PS->bitimage->FAX standard converter would be very nice (the program I
have converts only ASCII text to FAX.)  Any hints would be
appreciated.  Since this is a strange request, I'd be very pleased
with information pointing to such software running on any machine, not
just an Iris.
