Help with FT100 supercontrol program

Is anybody on the list running the FT100 Supercontrol program?  I am using
the 30 day trial of it right now, and like it, and am trying to set up the
voice keyer part of it.  However, I cannot find how to set the COM port to
put the rig in transmit when transmitting a voice message.  I have looked
through the  manual, and about every possible setting in the software with
no luck.

I can get rig control going ok, and the CW sending ok, but I just cannot
get the software to put the rig in transmit with a voice memory unless I
use the mic jack and put the rig in VOX.  There has to be a way to select
the COM port for PTT, I am sure, I just can't find it!
