Asynchronical serial: unable to read values 0x00 with PE routine

With the KE02 on CW IDE I'm trying to implement an RS232 component using the asynchronical serial component provided with the processor expert.

Having had enabled interrupts, and within the ISR calling the function <AS1_RecvChar> - generated by the processor expert - I am able to read any type of character with the exception the character NULL (0x00). 


Is there any reason why this may happen? Could it be that the interrupt is never called when a NULL is on the Rx?


Kind regards,
