>Description</H2
><P
>&#13;   This starts sending an arbitrary async packet. It gets an array of quadlets 
   consisting of header and data (without CRC in between). Header information 
   is always in machine byte order, data (data block as well as quadlet data 
   in a read response for data quadlet) shall be in big endian byte order. 
   expect_response indicates, if we expect a response (i.e. if we will get the 
   tag back after the packet was sent or after a response arrived). length is 
   the length of the complete packet (header_length + length of the data block).
   The main purpose of this function is to send responses for incoming 
   transactions, that are handled by the application.
   Do not use that function, unless you really know, what you do! Sending 
   corrupt packet may lead to weird results.
