Don't let the lightning protectors give you a false sense of security.
First, they offer no protection whatsoever unless connected to a proper
ground... and plugging them into a three-prong outlet is not adequate.

Even under the best conditions, they give limited protection.  And you
can still get lightning damage via the rs232 connection.  Lightning
doesn't always take the most direct path.
