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.
