The instrument responds to a valid command in the following format:
<STX>MD07<SP><address><BC1><SP><opStatus><SP><errStatus><SP>0000000000<SP>....
....
<address><BC7><SP><opStatus><SP><errStatus><SP>0000000000<SP><ETX><BCC><CR><LF>
<address> is the instrument address.
<BC1> ... <BC7> are 7 BC values, shown in exponential representation with 4 characters
mantissa and 2 characters exponent.
<opStatus> is the status of the operation state:
00000000 –measuring,
00000001 – tape advance,
