Hi Bjoern,

> sorry for my signing. I read that sometimes a different order is used within a byte as well and not only between bytes. 

I don't know of any architecture that stores the bits of its bytes in a
different order and where this is visible to for the user. However such
a platform might exists.

You mean big endian communicates with little endian or vice versa?

If you have a byte stream (a character array) then you don't need to
worry, because they are stored in a endianless format (bytewise). If you
use datatypes like uint16_t and uint32_t and send them to the stream or
copy them into an array then you should convert them to the same endian
encoding.

Regards

Marcel
