Greets all,
    The other day, I slotted my credit card at the local BP station.
 While I was waiting, I heard the distinct dialup sound of a modem and
 the telltale fuzz of information running across the line. There was no
 one in line behind me, and the guy didn't seem in a rush, so I asked
 him if there was a phone line running into his card verification device.
 He let me get a good look at it. Later that evening I returned with a 
 tape recorder and talked the guy into letting me get a recording of the
 tones. I have not yet tried to use my recording, but was curious if 
 anyone out there had fooled with this sort of thing before. The H/P croud
 around here had never heard of anyone experimenting with this before.
                     Lata,
                          Phain.
