You get a terminal server such as a Cyclades:

The nice thing about a serial port is that it is realistic to always
log everything even from a large amount of machines.  So it's quite
possible to build a central monitoring application that automatically
records oopses that appear on an serial console and forward them to
the system administrator, and with the logs the system administrator
could see what actions led up to the oops.

With 32-port terminal servers thats just a dozen of them.
