If the radio is OFF and you use the contact closure provision on the 
rear panel, it is indeed OFF.

If you use the alarm function, it is sleeping and drawing current. I 
don't recall the number offhand, but I think it is in the range of 50 to 
300 mA.

A "wake on serial port activity" would necessarily be in a similar 
range, which is part of the reason it doesn't yet -- and may not -- exist.
