What this is... it is the Clearwater International Airport.  The device
was a cloud height measuring laser.  I discovered the dialup wardialing.  
The fun part of it was that you had a couple options...  turning the laser
on, turning the blower on and opening the doors.  I decided that the worst
possible scenario would be to close the shutter doors, turn the blower off
and turn the laser on. This resulted in line noise and disconnection.  I
assume it over heated.  I could get connected again but only to see more
line noise and get disconnected again.  One of those things where someone
figured that an unlisted number would make things "safe".
