Help using Asynchroserial Bean

[JaimeR]

Hi, I've been trying  to use the AsynchroSerial bean with MC9S12XDP512. The communication is working,  I already configured the internal bus clock but I cant received certain chars, for example, when I send chars to the MCU sometimes the "received char" interruption is not generated and I have to send something different in order to generate the interruption (if I continue to send the same char nothing happens so it is not the buffer).   I also noticed that when I try to send a char starting with zero I received (on the receiver) something different to what I sent. I've been moving the settings of this bean playing with the width, setting it to 9 and 8 bits but when I use 9 I receive some bits OK but stop receiving others so this is not helping me either. For example:
                        8 bits width
                   I send        I received(on the receiver)
                   0x02          0x82
                   0xFB         0xFB
                         9 bits width
                   I send        I received(on the receiver)
                   0x02          0x02
                   0xFB         0x7B

I am also checking the signal on a oscilloscope but I don't understand it. I don't know if this signal is inverted and which bits are sent first.
The same thing happens with 115200 bauds and 9600 bauds.
I appreciate any help.

Thank you in advanced.
