Sets or returns the current transmit and receive configuration in the form
aaa.aaaabcc.ccccccdefghhhhhhiii.ijkllll.llllmnn.nnnnnnopqrsssssstuvv, where:
aaaa.aaaa=Tx Frequency (in MHz) (same as TFQ)
b=Tx Mode (same as TMM)
cc.cccccc=Tx Symbol Rate (same as TSR)
d=Tx FEC Type (same as TFT **)
e=Tx Modulation type (same as TMD)
f=Tx FEC Rate (same as TCR)
g=Tx Spectrum Inversion (same as TSI)
hhhhhh=Tx Gold Code Sequence (same as TGS)
iii.i=Tx Power Level (same as TPL)
j=Tx Carrier State (same as TXO)
k=Tx Alpha Roll-off (same as TAR)
llll.llll=Rx Frequency (in MHz) (same as RFQ)
m=Rx Mode (same as RMM)
nn.nnnnnn=Rx Symbol Rate (same as RSR)
o=Rx FEC Type (same as RFT **)
p=Rx Modulation type (same as RMD)
q=Rx FEC Rate (same as RCR)
x=spare
ssssss=Rx Gold Code Sequence (same as RGS)
t=Rx Alpha Roll-off (same as RAR)
u=Unit test Mode (same as TST**)
vv=Unit Alarm Mask (same as MSK)
NOTES:
1) ** indicates Read-only.
2) Unit returns 'x's for Rx parameters if unit is Modulator Only.
3) Unit returns 'x's for Tx parameters if unit is Demodulator Only.
4) If Rx is in DVB-S2 mode, the Rx Modulation Type and FEC rate are
ignored because these are automatically detected.
