MCF51JM128 and serial port

Hi everyone


I recently bought an MCF51JM128 microcontroller with a DEMOJM board.

I thought the J4 jumpers would connect the mini-USB port to the SCIx pins so that I could use it to send serial data from a PC. Although I installed pretty much every driver I found on the CD/usb key provided, the PC doesn't see any COM port.


According to the short tutorial I have to program the microcontroler to emulate the serial port. Isn't there some way to have the microcontroler think it's using SCIx and the PC think it's using a COMx port just using the DemoJM board ?


Sorry if it's a stupid question, but I thought it would be possible.
