Yes  , The  PC com-port is  one of the  keying  options , with the 
txd/dtr/rxd   being  selectable ,  two  com ports  may  be  selected , to 
allow for  station  tx/rx   and  data  keying    ( I think  the  same  port 
can be  selected  twice with  different  txd/dtr/rxd options selected for 
each  function) Gary may  use this ?)
The  other  option  is  the  conventional   audio/Rf  translation  by  way 
of   SSB Tx  , using  usb , the  audio  / carrier  frequency  using this 
facility is placed by a  scanning  routine  in the  lowest  s/n  part of the 
audio  band in use , to  prevent  collisions etc.
com-port keying  , is  as  per  normal  vfo/dds operation ,  ensuring  the 
carrier is  placed to  coincide  with the appropriate   rx audio  pass  band 
, when the  Rx is  set  usb  at the  normal  operating   qrg .
