Are you sure it's LPT?

MON08 is a serial protocol, it should be COM port.

 

Cheers,

Hi!

Yes, im sure, HC08 series can use both RS232  and LPT protocol to enter monitor mode.

 

 After power-on RESET it checks, if  PTA.0 is set to 1 and if so, enters SERIAL mode, else, it enters to LPT mode (if NOT PTE3 pin active, else it enters in USB mode).
