When the ventilator receives NPVS followed by a carriage return, it will respond
by transmitting the information shown in Table A-4: "Non-Invasive Positive
Pressure Ventilation Settings Report". The ventilator responds to the NPVS
command by returning a string with a variable length. Fields 2 through 4
define the length of the message. The last character transmitted is a stop code
indicating the end of the message. The second field indicates the number of
characters between the start and stop codes. The third field indicates the
number of fields between the start and stop codes. The fourth field is the start
code, 0x02. The last field in the string is the stop code, 0x03.
