Note that identical information is returned for any device ID that the Base
Radio has control of (i.e. including Transmitters mapped to virtual device
IDs when operating in the device ID mapping mode (See Section 6.2).
This command returns a two -byte status word and the device's event
counter. The status word will either be 0 or 65535 if the previous com-
mand is still being processed. The event counter is incremented for each
successful message received. The counter is not incremented for com-
mands that return exception responses or commands that fetch event
counters. The event counter will eventually roll over to 0 after reaching a
count of 65535. Note that identical information is returned for any device
ID that the Base Radio has control of (i.e. including Transmitters mapped
to virtual device IDs when operating in the device ID mapping mode).
For further details on this command, please consult the Modbus protocol
specification.
