gphoto2 and Polaroid PDC700 Camera - How?

[Scarletdown <gsutton9503@charter.net>]

Okay.  Now that I am up and running with Debian, I need to get my camera 
configured, so I can resume selling stuff on eBay.  My camera is an old 
Polaroid PDC-700, which connects to a serial port (COM1 in M$ terms, 
ttys0 in *nix terms).

I took a look at what cameras are supported by gphoto2, and it looks 
like this camera is allegedly supported.  However, when I installed 
gphoto2  (apt-get install gphoto2*), and then looked at the list of 
cameras (gphoto2 --list-cameras), the PDC700 did not show up as one of 
the available types.

So, how do I get gphoto2 to recognize my camera?  And then, how can I 
get GIMP to access the camera as an image source?
