The message may contain embedded 0x00's. To distinguish these embedded 
0x00's (and 0xFF's) from a terminating 0x00, embedded 0x00's and 0xFFare 
prefixed with a 0xFF byte. This means that when you process one byte at 
a time you have to perform a check on every byte. This results in 
totally unacceptable response times (My first version of this client was 
based on this approach)

The only alternative solution I can think off is to use C++ to create a 
socket and a function that reads from the socket. But since I have 
hardly any experience with C++ programming nor using the rcpp package....
