Anita,

You can toggle between channels using pfChanTravMode like in the
following fragment...
(Note: channels have been previously set up for each to take half the viewport)

      /*-------------------------------------------------
|-- Set the pfChannel to the active channel
      -------------------------------------------------*/
      if (activeChannel == CHANNEL_1)
      {
         /*--------------------------------------------
|-- Make sure the channel is on
         --------------------------------------------*/
         pfChanTravMode(channel, PFTRAV_DRAW, PFDRAW_ON);

         /*---------------------------------------
|-- Set the viewport one to full window
         ---------------------------------------*/
         pfChanViewport(channel, 0.0f, 1.0f, 0.0f, 1.0f);

         /*--------------------------------------------
|-- Turn off the other channel
         --------------------------------------------*/
         pfChanTravMode(channel2, PFTRAV_DRAW, PFDRAW_OFF);
      }

      else if (activeChannel == CHANNEL_2)
      {

         /*--------------------------------------------
|-- Make sure the channel is on
         --------------------------------------------*/
         pfChanTravMode(channel2, PFTRAV_DRAW, PFDRAW_ON);

         /*---------------------------------------
|-- Set the viewport two to full window
         ---------------------------------------*/
         pfChanViewport(channel2, 0.0f, 1.0f, 0.0f, 1.0f);

         /*--------------------------------------------
|-- Turn off the other channel
         --------------------------------------------*/
         pfChanTravMode(channel, PFTRAV_DRAW, PFDRAW_OFF);

      }
