Technical data

– <NR2>: Number with an embedded decimal point (0.1, 0.001. 3.3, etc.)
– <NR3>: Number with an embedded decimal point and exponent (1e33,
1.3e-12, etc.)
– Hex preceded by #h (#hff, #hFF, etc.)
• BOOLEAN
Boolean values can be sent to the Serial BERT as either ON | OFF or 0 | 1. The
Serial BERT answers queries with 0 | 1.
• BLOCK DATA
Block data is used when a large quantity of related data is being returned. A
definite length block is suitable for sending blocks of 8-bit binary information
when the length is known beforehand. An indefinite length block is suitable for
sending blocks of 8-bit binary information when the length is not known
beforehand or when computing the length beforehand is undesirable.
It has the following format:
#<Length of length><Length of data><data>
<Length of length> is a single integer that contains the number of digits in
<Length of data>, which in turn contains the length of the data. So, for example,
a 512-byte pattern would be defined as:
#3512<data>
