Actually I can't measure it, so it is below 1 uA, but only when there is 
no data.

1 transistor, 1 fet, 2 diodes, and some passives

At this state the Fet and transistor are off, and the negative tx signal 
is "stolen" from the incomming rx negative signal.

Its only good up to 57600 baud, so I'm thinking of changing it to a 
maxim chip.
