1 byte, value of 0 Command or Query
through 6 RX FEC Type, where:
0=Reserved
1=Viterbi
2=Viterbi + Reed-Solomon
3=Reserved
4=Reserved
5=TCM + Reed-Solomon
6=Turbo
Example: RFT=1 (Viterbi only)
1 byte, value of 0 Command or Query
through 5 RX Demodulator, where:
0=BPSK
1=QPSK
2=Reserved
3=8-PSK
4=16-QAM (Turbo or Viterbi + Reed-Solomon)
5=Reserved
Depending on FEC type, not all of these selections will be
valid. All other codes are invalid.
Example: RMD=1 (QPSK)
1 byte, value of 0 Command or Query
through 7 0=Rate 5/16 (Turbo Only)
1=Rate 21/44 (Turbo Only)
2=Rate 1/2
3=Rate 2/3 (8-Psk TCM or 8-QAM only)
4=Rate 3/4
5=Rate 7/8
6= Rate 17/18 (Turbo Only)
7= Reserved
Depending on FEC and demodulation type, not all of these
selections will be valid.
Example: RCR=4 (Rate 3/4)
