The absolute minimum number of leads is 2!  I have a friend with a
timesharing company, and he uses 2 wire cables for the VT100s around
the office: pins 2 & 3 and depends on the floating ground from the
power supplies to be within 3 volts or so (a safe assumption within
one building).  Never ceases to amaze me that it works fine.
