* If the three most significant bits of the command byte are not all 1, this indicates the first
group.
* The command is indicated by the three most significant bits:
* The fourth bit is the bit for parameter extension. When this bit is 0, this means that the
parameter(s) embedded in the command byte are the command parameters just as they stand,
while when this bit is 1, this means that the parameter embedded in the command byte is the
number of subsequent parameter bytes.
The <XFER> command is an exception, and, only for this command, the parameter means the
subsequent number of bytes of the image data after compression.
