What are you trying to do here?

What is the purpose of sending messages back to the bdm interface?

And finally which CPU are you targeting (HC08, HC12, Coldfire, ..)?
Which version of CodeWarrior are you using?

To retrieve that info:
- Start CodeWarrior
- Select Help -> About Freescale CodeWarrior
- Click on "Install Products"
- CodeWarrior version used is displayed on top in the Installed Products dialog.

Hi Danzo,

The BDM interface present in the DEMOQE boards (maybe DEMOJM too, but I don't have one here) implements a virtual serial port through the same USB connection used by the debugging hardware.

Unfortunatelly, the host side uses a proprietary application interface. As far as I know, there is no documentation about using such feature (from the host point of view). Maybe the guys at P&E Micro could add a virtual COM port driver to enable easier use of this resource.

Best regards,
