I imagine this will work but am not totally certain...

Initialize both COM ports identically with a program such as MODE
or Kermit.  Then connect them together in parallel with a custom
made cable.  Pin 1 of one port should be connected to pin 1 of 
the other.  Same goes for all the other pins you use, which are
2, 3, 7, and perhaps 6 and 20.
