Buffer is a pointer into a series of

overwritten with the number of bytes left that were not consumed, and the
return value is as follows:
0: Still looking for something...
1: An output byte was received and stored in outbyte
-1: An error occured in the transmission
overwritten with the number of bytes left that were not consumed.
\return return value is as follows:

\arg -1: An error occured in the transmission
He must be called with at least 80 bytes of buffer. */
