Any particular reason that RS232C has to be the linkup?  There are 
plenty of external drives that can use the parallel port with regular 
software.  For example, hook up a ZIP drive.

Alternatively, you could boot DOS from floppy with INTERLINK/INTERSVR 
installed and use another DOS/WIN machine to do your backup.

I'm certain that options abound.
