* The framer expects a fixed length header of 2 16-bit shorts
* containing the payload length, followed by the payload. If the
* 2 16-bit shorts are not identical, this packet is
* ignored. Better algs are welcome.
*
* The input data consists of bytes that have two bits used. Bit
* 0, the LSB, contains the data bit. Bit 1 if set, indicates that
* the corresponding bit is the the first bit of the packet. That
* is, this bit is the first one after the access code.
