My first guess is that you have a getty running on /dev/ttyS0.  That  
would allow you to login over the serial port with minicom.  However,  
it would interfere with other uses of the /dev/ttyS0, including  
talking to the pioneer.  If this is the case, you need to kill the  
getty before starting Player.
