Global configuration, in the form:
aaa.aaaabcc.ccccccdefghhhhhhiii.ijkllll.llllmnn.nnnnnnopqrsssssstuvv, where:
aaaa.aaaa = Tx Frequency (in MHz)
b = Tx Mode
cc.cccccc = Tx Symbol Rate
d = Tx FEC Type
e = Tx Modulation type
f = Tx FEC Rate
g = Tx Spectrum Inversion
hhhhhh = Tx Gold Code Sequence
iii.i = Tx Power Level
j = Tx Carrier State
k = Tx Alpha Roll-off
llll.llll = Rx Frequency (in MHz)
m = Rx Mode
nn.nnnnnn = Rx Symbol Rate
o = Rx FEC Type
p = Rx Modulation type
q = Rx FEC Rate
x = spare
ssssss = Rx Gold Code Sequence
t = Rx Alpha Roll-off
u = Unit test Mode
vv = Unit Alarm Mask

Returns current transmit and
receive configuration.
Notes:
1. Unit returns 'x's for Rx
parameters if unit is modulator
only.
2. Unit returns 'x's for Tx
parameters if unit is
demodulator only.
3. If Rx is in DVB-S2 mode,
the Rx Modulation Type and
Rx FEC Rate is ignored
because these are
automatically detected.
