[CQ-Contest] CW equipment question

    I've recently acquired a new radio for the N5XU VHF contest station.
Unlike our other radios, this one requires manually toggling the PTT
line while sending CW.

    We use a Super CMOS Keyer III for the VHF radios.  I think it would be 
great if I could have the keyer handle a PTT line in addition to the keying
line, much like TR Log can do from a parallel port CW interface.  The Super 
CMOS Keyer III does not do this currently.  

    Does anyone have ideas/sources for a circuit I could add to the keyer to
do this?
