I haven't used DriveWire for a few years, so I can't remember the  
commands correctly or even test this out...

I think the basic idea of copying virtual disk images from a PC  
through DriveWire onto a CoCo with floppy goes something like this:

DRIVE ON
DSKINI 4
BACKUP 0 TO 4
DRIVE OFF
BACKUP 4 TO 0

Mount the disk image you are interested in in DriveWire.  Create a  
blank, high-numbered virtual floppy to temporarily hold the disk image  
(e.g. virtual disk #4 in this case).  Copy the virtual disk image up  
to this temporary space (e.g. from virtual disk #0 to #4).  Then  
disengage DriveWire from commandeering the real floppy drive numbers,  
and backup that temporary virtual floppy onto a real floppy in the CoCo.
