• HDLC_OVERRUN - a byte was overwritten and lost before the ISR could retreive it.

• HDLC_OVERFLOW - a received packet was too long for the buffers.

• HDLC_ABORTED - a received packet was aborted by the sender during tranmission.

• HDLC_BADCRC - a packet with an incorrect CRC was received.

This function is intended for use with the Rabbit 3000 and Rabbit 4000.
