The format of the RD_1 output is a space-separated sequence of 2-digit hexadecimal representations of the individual bytes in the receive buffer. Since the buffer is zero-filled before message reception, the output string terminates with the characters "..." following the first zero byte in the set of contiguous zero bytes to the end of the buffer. Thus, if the message contains trailing zero bytes, only the first is shown.
See the CODEC_TEST system configuration for an example of the use of an instance of this type.
