Alarm Status Report
(ALRM)

When the ventilator receives ALRM followed by a carriage return, it will
respond by transmitting the information shown in Table A-6: “Alarm Status
Report”. The ventilator responds to the ALRM 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.
