Verification via SMS

The current Comm, GPS and Inbound status of either a CDMA or GSM LMU can be
obtained via SMS provided you have access to an SMS capable phone or PDA.
Using your handset, send the following SMS Message to the LMU:
!R0
Within a few minutes, the LMU should return a response in the following format:
APP: <App ID> <Firmware Version>
COM:<RSSI> [./d/D][./a/A][./L][IP address] [<APN>]
GPS:[Antenna <Short/Open/Off>] | [No Time Sync] |
[<FixStatus> <Sat Count>]
INP:<inputs states> <vehicle voltage>
MID:<mobile ID> <mobile ID type>
INB:<inbound IP address>:<inbound port> <Inbound
Protocol (LMD/LMX)>
 APP:
o <App ID>:
The Application ID value of the LMU indicating the host platform and the
wireless networking technology of the LMU.
o <Firmware Version>:
The current firmware version in use by the LMU
 COM:
o <RSSI>:
This is the signal strength the wireless modem sees from the network. In
general the LMU is at least scanning for the network if the RSSI is not -113.
o [./d/D]:
If the character 'D' is present, it indicates the LMU had a data session
established when it responded to the status request. For the 8-Bit product line
an upper case 'D' indicates both the Inbound and Maintenance sockets are
ready. The lower case 'd' indicates that only the Maintenance socket is ready.
A '.' indicates no sockets are ready.
o [./a/A]:
This field indicates if the LMU has received an Acknowledgement from the
Inbound server. This field will be empty if the LMU has never received an
ACK.The lower case 'a' will be present if it has received an ACK since the last
cold boot (i.e. power cycle) but not the last warm boot (App Restart or Sleep).
The upper case 'A' will be present if the LMU has received an ACK since the
last warm boot. A '.' Indicates no acknowledgement has been received.
