Well I figured out what the problem is. I have a parity error in the  
PD_STS?Primary Device Status Register 0x06 and can't clear the bit 15.  
When I try it just goes back to 0x8080. I am supposed to be able to  
clear this bit by writing a 1 to the bit location. Why won't it let me  
clear this bit?? Hugh...this is so frustrating...I am so close:-(


Thanks - Joe
