If you use really long RS-232 cables, it's pretty easy for someone to tap
the line and capture everything. If the terminals are in other rooms, and
the cables go somewhere an attacker could get at them, you could be sniffed.
See "the cuckoo's egg" for an example of doing this. (He used
printer/terminals, but you could use a laptop or two with a serial port for
each direction of the connection to capture everything even at high speed.)
