Hi,
there is a code in function *dvbsat_diseqc_set_input*:
[...]
/* Negative numbers means to not use a DiSEqC switch */
if (parms->p.sat_number < 0)
return 0;
[...]
if it mean /there is no DiSEqC switch/ then LNB's *polarity* and *band*
settings still should be applied - attached patch fixes that behavior.
if it mean /current DVB is a slave/ i.e. it is connected to LOOP OUT of
another DVB, so no need to configure anything, then statement above is
correct and no patches from this email should be applied.
