Stored
Statistics N/A 135 bytes Query only.
Unit returns the oldest 5 Stored Statistics, which have not yet been
read over the remote control, in the reply form:[CR]Sub-body[CR]
Sub-body[CR]Sub-body[CR]Sub-body[CR]Sub-body;
Sub-body = AA.ABB.BC.CD.Dddmmyyhhmmss, where:
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 less than 5 statistics to be retrieved, the remaining positions
are padded with zeros. If there are no new events, the unit replies with
RNS*.

ESC
parameters SCP= 2 bytes,
numeric
Command or Query.
(IBS and ESC++ parameter)
Allows control of the ESC baud rate and character format, where x is
the ESC baud rate:
0=1200 baud
1=2400 baud
2=4800 baud
3=9600 baud
4=19200 baud
5=38400 baud
6=14400 baud
7=28800 baud
and y is the character format (data bits, parity bits, stop bits):
0= 8-N-1 (parity=none)
1= 7-E-2 (parity=even)
2= 7-O-2 (parity=odd)
The ESC baud rate breakpoints (determined by data rate) are shown
in Chapters 5 and 10. A response of SCP* will indicate if the data rate
will not allow a selected baud rate to operate.

Sample
Interval SSI= 1 byte,
numerical Command or Query.
Used to set the sample interval for the Statistics Logging Function, in 10-
minute increments, in the form x, where:
x= 0-9
Note: Setting this parameter to 0 disables the statistics logging function.
Example: SSI=3 means 30 minutes
