[Elecraft] The state of a latching relay

[Sverre Holm - LA3ZA]

If I understand right, the latching relays in the K1 and K2 change state
every time you give them current for a short while, and then stay in the
new position until the next impulse is given to them. To my mind this
makes it impossible to figure out which position they are in, but I'm
probably missing something here. 

So the question to the clever ones is: How does the firmware in the K's
know the relay settings?
