l The query returns Definite Length Block Data, which allows any type of data to be transmitted as a
series of 8-bit data bytes. The first line is a pound sign (#) followed by one digit representing the num-
ber of digits in the decimal integer to follow. This digit is followed by a decimal integer indicating the
number of data bytes to follow, followed by the first New Line. (For example, "#47947" in the first line
means that there are 7947 data bytes to follow.) The rest of the block has one command per line, each
terminated by a New Line character (ASCII character 10).
