I've come across a website discussing connection of a USB CD-ROM drive to a DOS
system for booting purposes but I've not seen reference to serial devices. I
think the people to ask about this might be Parallax since they use
USB-connected serial ports for device programming, if anybody knows how to hook
them onto older machines they will.

My own feeling if you /have/ to have a DOS environment and don't mean something
like the '98 DOS box would be to see if you could run the code under either
DosEmu or Qemu, both of which allow guest session ports to be mapped to whatever
hardware is supported by the host. I've got one system here where DosEmu has
been set up to allow software direct access to an lpt port so it can control an
EPROM blaster, but obviously that sort of thing wouldn't work where the physical
device types differed.
