Retrieve next 5
unread Stored
Statistics N/A 130 bytes Query only
Unit returns the oldest 5 Stored Statistics which have not yet
been read over the remote control. Reply format:
{CR}Sub-body{CR}Sub-body{CR}Sub-body{CR}Sub-
body{CR}Sub-body, where Sub-body=
AA.ABB.BC.CD.Dddmmyyhhmmss,
AA.A = Minimum Eb/No during sample period.
BB.B = Average Eb/No during sample period.
C.C = Max. Tx Power Level Increase during sample period.
D.D = Average Tx Power Level Increase during sample period.
ddmmyyhhmmss = date/time stamp.
If there are no new events, the unit replies with RNS* If there are
less than 5 statistics to be retrieved, the remaining positions are
padded with zeros. N/A RNS? RNS={CR}AA.A

of unread Stored
Statistics N/A 3 bytes,
numerical
Query only.
Unit returns the number of Stored Statistics which remain
unread, in the form xxx. Note: This means unread over the
remote control - viewing the stored events from the front panel
of the modem does not affect this value.
Example reply: NUS=198 N/A NUS? NUS=xxx (see
description for
details of
arguments)
Clear All Stored
Statistics CAS= None Command only
Instructs the unit to clear all Stored Statistics
This command takes no arguments.
CAS= (message ok) N/A N/A
Local/Remote
Status LRS= 1 byte, value of 0
or 1 Command or Query (Command only if S/W > 1.13)
As a query, returns the local/remote status of the unit, where:
0 = local
1= remote
When used as a comand, uses the same codes for an
argument.
Example: LRS=1 (unit is in remote mode) LRS=
(message ok) LRS? LRS=x (see
description for
details of
arguments)
Serial Number SNO= 4 bytes
numerical
0000 to 9999 Command portion is FACTORY USE ONLY.
Used to set or Query the units 4 digit serial number.
Unit returns its S/N, in the form xxxx.
Example: SNO=1765 (1
ST 4 DIGITS OF ESN – 9 DIGIT S/N)
SNO= (message ok) SNO? SNO=xxxx (see
description for
details of
arguments)
