The Symmetricom 5087B automatically publishes alarms to the CNR
port as they occur.
The alarms appear in the format ALARMabcde where abcde is the
summary status of the input and output signals. The format of the alarm
status is identical to the "S" command response defined in
page 23.
Example: ALARM00003
This example shows that outputs 1 and 2 have active faults.
