[comp.windows.x] Fax bitmap server

thinman@cup.portal.com (Lance C Norskog) (08/06/90)

I have a really unpleasant idea:  what if someone rigged up the fax modem
on their computer so that anybody could fax them a picture, and get e-mailed
back a digitized image?

I supposed you would want to use the PPM or GIF format, uuencoded.

I still can't figure out how to get the return e-mail address automatically,
though...

An unnamed source says that faxes have something called a CSI, limited
to 20 characters, that the sender gives to the receiver.  Usually this
is set to the caller's fax phone number.

If I were setting this up, I would want to maintain a registry of possible
callers just for my own protection, and to be able to control my outgoing
mail flow; so a database of (fax number, real name, network address,
route) tuples would be the handiest method.

I used the word 'unpleasant' because I was worried about the possible
amount of non-scholarly traffic that this service could generate...
bitmaps are big.

GIFmaps are rather reasonable in size, however.  Excellent compression.
