Hmm. That document is EXTREMELY misleading, but does finally confirm 
that you can't either *modem or TFTP. I believe the so-called "TFTP" 
capability the document author refers to for the MSFC3/sup720 is the 
TFTP client in the bootflash image.

"""As the Recover a Supervisor Engine 720 from a Missing/Corrupted Cisco 
IOS Image or ROMmon Mode section mentions, the Supervisor Engine 720 
does not support the Xmodem recovery procedure.

Therefore, always keep a copy of the image in disk0 or disk1, or the 
MSFC boot Flash. If you do not have any copies on either disk0 or disk1 
and you encounter the problem of a missing/corrupted image, the only way 
to recover is to copy the image on the Flash disk from another switch."""

The ROMmon on *my* spare box most certainly does NOT have TFTP capability:
