I'm experiencing some trouble with S12UB (product codes: LFEBS12UB and LFEBS12UBLAB).

The stand-alone kit, provide 21 labs, to get started with 9S12 architcture.


The first lab (attached)  just provide the basic information to connect the debug12 module with the PC through HyperTerminal. I follow all instructions (baud=9600, 8 bits data, no parity, 1 stop bit, xon/xoff etc.), but instead of visualizing the d-bug12 bootloader, i just recive from serial port random ASCII characters.


I tried to change baud, connect in different ways the MODE pins, but i always get the same problem.


i don't have a serial port on my PC, but i emulate it wit a prolific USB-to-Serial properly configured.


I also don't have no idea, about what pin i have to connect with jumpers (if i have to do it).


Is there some specific instruction manual for S12UB?

Is it possible that data in FLASH/EEPROM memory are corrupted? how can i do to rewrite the d-bug12 program in the uC?
