DEFINITION: The signature is a four-digit-long hexadecimal value that can be optionally placed before
every command to keep a command and the corresponding responses together as a group.
Each line is terminated with a carriage return (Cr, β€˜\r’) and line feed (Lf, β€˜\n’) characters. In several cases the
number of the lines in the response cannot be determined in advance, e.g. the client intends to receive for the
whole response and also wants to be sure, that the received lines belong together and to the same command.
In these cases, a special feature the β€˜signature’ can be used. The response to that particular command will
also be preceded by the signature, and the corresponding lines will be between brackets:
