319 * QPSK FEC_3_4 0x08 0x02+X DVB-S
320 * QPSK FEC_4_5 0x10 0x02+X DVB-S (?)
321 * QPSK FEC_5_6 0x20 0x02+X DVB-S

328 * and low byte selects the modulator. The high
329 * byte is search range mask. Bit 5 may turn
330 * on DVB-S and remaining bits represent some
331 * kind of calibration (how/what i do not know).

339 * status 1f | signal c3c0 | snr a333 | ber 00000000 | unc 0 | FE_HAS_LOCK
341 * After tuning FECSTATUS contains actual FEC
342 * in use numbered 1 through to 8 for 1/2 .. 2/3 etc

349 * NBC-QPSK FEC_3_4 0x00, 0x07 DVB-S2
350 * NBC-QPSK FEC_4_5 0x00, 0x08 DVB-S2
351 * NBC-QPSK FEC_5_6 0x00, 0x09 DVB-S2
352 * NBC-QPSK FEC_8_9 0x00, 0x0a DVB-S2
353 * NBC-QPSK FEC_9_10 0x00, 0x0b DVB-S2
