Report (PCVS)
When the ventilator receives PCVS followed by a carriage return, it will respond
by transmitting the information shown in Table A-3: “Pressure Control
Ventilation Settings Report”. The ventilator responds to the PCVS 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.
