Using a pin-out diagram from somewhere on-line, I built a 'null hub' in a
2-jack phone jack.  It allows use of standard cables.

If you number the pins 87654321 as you look at the 'business end' of each jack,
connect pin 6 to pin 2, and pin 3 to pin 1 (do the same starting at the 2nd
jack).

This works nicely for 2 devices.

Does anyone have a pinout diagram for 3 or more devices, or does this
require active circuitry?
