314 * QPSK FEC_1_2 0x02 0x02+X DVB-S
315 * QPSK FEC_2_3 0x04 0x02+X DVB-S
316 * QPSK FEC_3_4 0x08 0x02+X DVB-S
317 * QPSK FEC_4_5 0x10 0x02+X DVB-S (?)
318 * QPSK FEC_5_6 0x20 0x02+X DVB-S
319 * QPSK FEC_6_7 0x40 0x02+X DVB-S
320 * QPSK FEC_7_8 0x80 0x02+X DVB-S

322 * QPSK AUTO 0xff 0x02+X DVB-S
324 * For DVB-S high byte probably represents FEC
325 * and low byte selects the modulator. The high
326 * byte is search range mask. Bit 5 may turn
327 * on DVB-S and remaining bits represent some
328 * kind of calibration (how/what i do not know).
330 * Eg.(2/3) szap "Zone Horror"

335 * mask/val = 0x04, 0x30
336 * status 1f | signal c3c0 | snr a333 | ber 00000000 | unc 0 | FE_HAS_LOCK
338 * After tuning FECSTATUS contains actual FEC
339 * in use numbered 1 through to 8 for 1/2 .. 2/3 etc
341 * NBC=NOT/NON BACKWARD COMPATIBLE WITH DVB-S (DVB-S2 only)

346 * NBC-QPSK FEC_3_4 0x00, 0x07 DVB-S2
347 * NBC-QPSK FEC_4_5 0x00, 0x08 DVB-S2
348 * NBC-QPSK FEC_5_6 0x00, 0x09 DVB-S2
349 * NBC-QPSK FEC_8_9 0x00, 0x0a DVB-S2
350 * NBC-QPSK FEC_9_10 0x00, 0x0b DVB-S2
352 * NBC-8PSK FEC_3_5 0x00, 0x0c DVB-S2
353 * NBC-8PSK FEC_2_3 0x00, 0x0d DVB-S2
354 * NBC-8PSK FEC_3_4 0x00, 0x0e DVB-S2
355 * NBC-8PSK FEC_5_6 0x00, 0x0f DVB-S2

360 * and FEC. High byte is meaningless here. To
